| Three-dimensional photonic crystal simultaneously integrating a nanocavity laser and waveguides |
| T. Tajiri, S. Takahashi, Y. Ota, K. Watanabe, S. Iwamoto, and Y. Arakawa |
| Optica 6(3), 296-299 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| Three-dimensional photonic crystals with complete photonic band gaps enable full control of light and thus are a promising platform for three-dimensional integrated photonic circuits. The authors fabricated such a crystal, integrating a nanocavity laser and waveguides, and successfully guided near-infrared light from the nanocavity laser via the waveguides. |
| Functional retinal imaging using adaptive optics swept-source OCT at 1.6 MHz |
| Mehdi Azimipour, Justin V. Migacz, Robert J. Zawadzki, John S. Werner, and Ravi S. Jonnal |
| Optica 6(3), 300-303 (2019) View: HTML | PDF |
| There are a number of proposed regenerative therapeutic approaches to treat photoreceptor loss and dysfunction due to retinal disease. Assessment of disease progression and therapeutic efficacy requires objective, noninvasive methods for imaging these cells and assessing their functional responses. The authors describe such a technique, based on optical coherence tomography and adaptive optics and demonstrate its effectiveness at measuring human photoreceptor function. |
| High-speed polarization-resolved third-harmonic microscopy |
| Joséphine Morizet, Guillaume Ducourthial, Willy Supatto, Arthur Boutillon, Renaud Legouis, Marie-Claire Schanne-Klein, Chiara Stringari, and Emmanuel Beaurepaire |
| Optica 6(3), 385-388 (2019) View: HTML | PDF [Suppl. Mat. (4)] |
| Third harmonic generation microscopy provides 3D label-free images of thick objects such as biological tissues. By combining it with a fast polarization control system, the authors show that it can also map dynamically optical anisotropy in deforming samples, potentially facilitating the study of molecular organization and mineralization processes in vivo. |
| Mapping and measuring large-scale photonic correlation with single-photon imaging |
| Ke Sun, Jun Gao, Ming-Ming Cao, Zhi-Qiang Jiao, Yu Liu, Zhan-Ming Li, Eilon Poem, Andreas Eckstein, Ruo-Jing Ren, Xiao-Ling Pang, Hao Tang, Ian A. Walmsley, and Xian-Min Jin |
| Optica 6(3), 244-249 (2019) View: HTML | PDF [Suppl. Mat. (2)] |
| The authors present a general and large-scale approach for mapping and measuring photonic correlation using direct single-photon imaging, called Correlation on Spatially-mapped Photon-Level Image. This technique can unify the measurement of quantum correlation in position, time, frequency, and polarization with the capability of addressing thousands of modes, and could boost quantum-enhanced technologies, especially for building large-scale photonic quantum computers. |
| Angular-spectrum modeling of focusing light inside scattering media by optical phase conjugation |
| Jiamiao Yang, Jingwei Li, Sailing He, and Lihong V. Wang |
| Optica 6(3), 250-256 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| Wavefront shaping refocuses light inside scattering media by compensating for the wave disturbance. However, no existing physical models explain the impact of the various factors on focusing performance. By adopting the angular-spectrum method, the authors established a model to trace the light field propagation in scattering media and investigated all the factors influencing focusing performance. |
| Optimal simultaneous measurements of incompatible observables of a single photon |
| Adetunmise C. Dada, Will McCutcheon, Erika Andersson, Jonathan Crickmore, Ittoop Puthoor, Brian D. Gerardot, Alex McMillan, John Rarity, and Ruth Oulton |
| Optica 6(3), 257-263 (2019) View: HTML | PDF |
| Using single photons, the authors report a simple technique for four-outcome simultaneous quantum measurement of two incompatible observables on a qubit. They probed a fundamental uncertainty relation governing such measurements and demonstrated measurement uncertainties at the fundamental limits set by quantum mechanics. That they could realize such quantum-limited simultaneous measurements in this way has implications for quantum metrology, as well as other emerging quantum technologies relying on quantum state estimation. |
| Demonstration of topologically path-independent anyonic braiding in a nine-qubit planar code |
| Chang Liu, He-Liang Huang, Chao Chen, Bi-Ying Wang, Xi-Lin Wang, Tao Yang, Li Li, Nai-Le Liu, Jonathan P. Dowling, Tim Byrnes, Chao-Yang Lu, and Jian-Wei Pan |
| Optica 6(3), 264-268 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| Anyons form the basis for topological quantum computation and error correction, where the topological aspect of anyonic braiding is one of the important features that gives rise to fault tolerance. The authors demonstrate the topologically path-independent property of anyonic braiding operations using a nine-qubit photonic system, enabling further exploration of the features of anyonic statistics with linear optics. |
| Mapping complex mode volumes with cavity perturbation theory |
| K. G. Cognée, W. Yan, F. La China, D. Balestri, F. Intonti, M. Gurioli, A. F. Koenderink, and P. Lalanne |
| Optica 6(3), 269-273 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| The main figures of merit for microcavities and nanoresonators are their Q’s and V’s. Q’s are well-defined quantities. By using cavity perturbation theory, the authors provide a definition of V’s, show that it is a complex number, measure its real and imaginary parts, and interpret the significance of each part. |
| Rapid broadband characterization of scattering medium using hyperspectral imaging |
| Antoine Boniface, Ivan Gusachenko, Kishan Dholakia, and Sylvain Gigan |
| Optica 6(3), 274-279 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| It’s possible to control the propagation of an ultrashort pulse of light through a thick scattering medium if one has knowledge of the spectrally dependent transmission matrix. The authors report a hundred-fold increase in measurement speed of a hyperspectral imaging system to refocus light in both space and time, facilitating potential developments in imaging. |
| Towards intense isolated attosecond pulses from relativistic surface high harmonics |
| Olga Jahn, Vyacheslav E. Leshchenko, Paraskevas Tzallas, Alexander Kessel, Mathias Krüger, Andreas Münzer, Sergei A. Trushin, George D. Tsakiris, Subhendu Kahaly, Dmitrii Kormin, Laszlo Veisz, Vladimir Pervak, Ferenc Krausz, Zsuzsanna Major, and Stefan Karsch |
| Optica 6(3), 280-287 (2019) View: HTML | PDF [Suppl. Mat. (2)] |
| Relativistic surface high-order harmonic generation (RSHHG) is a promising source of intense isolated attosecond pulses. However, its potential has not yet been exploited due to the complexity of its practical realization and the necessity of multi-parameter optimization. The authors report progress in this regard by experimental identification of optimum conditions for the RSHHG process and show that a driving field consisting of three optical cycles can result in an isolated attosecond pulse via RSHHG. |
| Experimental multiphase estimation on a chip |
| Emanuele Polino, Martina Riva, Mauro Valeri, Raffaele Silvestri, Giacomo Corrielli, Andrea Crespi, Nicolò Spagnolo, Roberto Osellame, and Fabio Sciarrino |
| Optica 6(3), 288-295 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| Using femtosecond laser writing, the authors realized a tunable integrated three-arm interferometer that allowed simultaneous estimation of the two embedded relative phase shifts. This platform could be a testbed for quantum multiphase estimation, with applications to quantum imaging, gravitational wave detection, and measurement of biological samples. |
| Soliton self-mode conversion: revisiting Raman scattering of ultrashort pulses |
| L. Rishøj, B. Tai, P. Kristensen, and S. Ramachandran |
| Optica 6(3), 304-308 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| The authors describe the discovery of a manifestation of Raman scattering of ultrashort pulses that happens in multimode, and not conventional singlemode, waveguides. Soliton self-mode conversion enables wideband frequency translations of record power femtosecond pulses while maintaining high modal, and hence spatial, purity. This self-organized nonlinear phenomenon facilitates the development of fiber-based high-energy ultrashort pulse sources at different wavelengths, on-demand. |
| Stable single light bullets and vortices and their active control in cold Rydberg gases |
| Zhengyang Bai, Weibin Li, and Guoxiang Huang |
| Optica 6(3), 309-317 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| This article presents a scheme to obtain stable single light bullets and vortices and realize their storage and retrieval in a cold Rydberg atomic gas. This could enable understanding and manipulation of high dimensional nonlinear optical processes via controlled local and nonlocal optical Kerr nonlinearities using new states of matter, and could have practical applications in quantum information processing and transmission. |
| Effect of strong coupling on photodegradation of the semiconducting polymer P3HT |
| Vanessa N. Peters, Md Omar Faruk, Joshua Asane, Rohan Alexander, D’angelo A. Peters, Srujana Prayakarao, Sangeeta Rout, and M. A. Noginov |
| Optica 6(3), 318-325 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| This article combines optical, chemical, and quantum electrodynamics phenomena to show that strong coupling of the semiconducting polymer P3HT with a resonant Fabry-Perot cavity slows down the polymer's photodegradation. The demonstrated effect was stronger than that in the weak coupling regime, and could lead to greater control of chemical reactions and catalysis with light-matter interactions. |
| One-lens camera using a biologically based artificial compound eye with multiple focal lengths |
| Wei-Lun Liang, Jun-Gu Pan, and Guo-Dung J. Su |
| Optica 6(3), 326-334 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| This paper describes a one-lens camera that uses a biologically inspired artificial compound eye with multiple focal lengths. Unlike traditional camera designs, which consist of many separate lenses and are difficult to assemble due to tight tolerance, this one monolithically integrates micro-lenses on a curved surface to ease alignment. This design allows assembly of a compact and wide field-of-view camera module. |
| Scalable feedback control of single photon sources for photonic quantum technologies |
| Jacques Carolan, Uttara Chakraborty, Nicholas C. Harris, Mihir Pant, Tom Baehr-Jones, Michael Hochberg, and Dirk Englund |
| Optica 6(3), 335-340 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| The authors developed an on-chip feedback mechanism to stabilize the generation of arrays of single photons. The method provides a compact, fast, and scalable way to generate the many millions of single photons required for large-scale quantum technologies. |
| Fast compressive Raman bio-imaging via matrix completion |
| Fernando Soldevila, Jonathan Dong, Enrique Tajahuerce, Sylvain Gigan, and Hilton B. de Aguiar |
| Optica 6(3), 341-346 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| Spontaneous Raman imaging is a powerful label-free technique with high chemical selectivity. However, it is remarkably slow due to its weak signal levels and large data sets. The authors present a new method for compressive Raman microspectroscopy enabling fast imaging with high data size compressions. |
| Resolution-enhanced quantum imaging by centroid estimation of biphotons |
| Ermes Toninelli, Paul-Antoine Moreau, Thomas Gregory, Adam Mihalyi, Matthew Edgar, Neal Radwell, and Miles Padgett |
| Optica 6(3), 347-353 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| The resolution of a conventional microscope is fundamentally limited by the finite-size of the imaging lens. The authors show that, by using pairs of entangled photons as the illumination source, and using only these photon pairs to define the image, it is possible to increase the resolution of the microscope, potentially by a factor of √2. |
| Strong coupling of ionizing transitions |
| Erika Cortese, Iacopo Carusotto, Raffaele Colombelli, and Simone De Liberato |
| Optica 6(3), 354-361 (2019) View: HTML | PDF [Suppl. Mat. (1)] |
| The authors show how a bound-to-continuum ionizing electronic transition can be strongly coupled to a photonic resonator. This leads to the appearance of novel discrete resonances, corresponding to bound excitons whose electron and hole are kept together by the exchange of virtual cavity photons. |
| Intelligent programmable mode-locked fiber laser with a human-like algorithm |
| Guoqing Pu, Lilin Yi, Li Zhang, and Weisheng Hu |
| Optica 6(3), 362-369 (2019) View: HTML | PDF |
| Inspired by the manual mode-locking tuning process, the authors propose a human-like algorithm to create an intelligent, programmable, mode-locked fiber laser that is capable of automatically locking onto various regimes. When combined with real-time feedback control, the intelligent laser substantially improves initial mode-locking time and recover time from disturbance. |
| IsoSense: frequency enhanced sensorless adaptive optics through structured illumination |
| Mantas Žurauskas, Ian M. Dobbie, Richard M. Parton, Mick A. Phillips, Antonia Göhler, Ilan Davis, and Martin J. Booth |
| Optica 6(3), 370-379 (2019) View: HTML | PDF |
| IsoSense is a wavefront sensing method that mitigates sample dependency in image-based sensorless adaptive optics applications in microscopy. The technique employs structured illumination to create additional high spatial frequencies in the image through custom illumination patterns. This significantly improves the reliability of image quality metric calculations and enables sensorless wavefront measurement, even in samples with sparse spatial frequency content. |

| Boris Desiatov, Amirhassan Shams-Ansari, Mian Zhang, Cheng Wang, and Marko Lončar |
| Optica 6(3), 380-384 (2019) View: HTML | PDF |
| Low-loss integrated photonic platforms operating at visible wavelengths are of great interest for applications ranging from quantum optics and metrology to biosensing and biomedicine. Using an optimized design and fabrication process, the authors developed a monolithic ultra-low-loss platform at visible wavelengths in a thin-film lithium niobate chip. |
