Title: Noise correlation and success probability in coherent Ising machines [arXiv, PDF] Authors: Yoshitaka Inui and Yoshihisa Yamamoto Submitted on 23 September 2020. Abstract: We compared the noise correlation and the success probability of coherent Ising machines (CIMs) with optical delay-line, measurement feedback, and mean-field couplings. We theoretically studied three metrics for the noise correlations in

Applied, arXiv, PDF] Authors: Dodd Gray, Ryan Hamerly, Meysam Namdari, Mircea-Traian Cătuneau, Nate Bogdanowicz, Hideo Mabuchi, Kambiz Jamshidi Published on 25 August 2020. Abstract: We demonstrate voltage-tunable thermo-optic bi- and tri-stability in silicon photonic microring resonators with lateral p-i-n junctions and present

Title: Engineering a Kerr-based Deterministic Cubic Phase Gate via Gaussian Operations [PRL, arXiv, PDF] Authors: Ryotatsu Yanagimoto, Tatsuhiro Onodera, Edwin Ng, Logan G. Wright, Peter L. McMahon, Hideo Mabuchi Journal: Physical Review Letters 124, 240503 (2020) Published on 18 June 2020.

Title: Petermann-factor limited sensing near an exceptional point (arXiv, PDF) Authors: Heming Wang, Yu-Hung Lai, Zhiquan Yuan, Myoung-Gyun Suh, Kerry Vahala Submitted on 8 Nov 2019. Abstract: Non-Hermitian Hamiltonians describing open systems can feature singularities called exceptional points (EPs). Resonant frequencies become strongly dependent on externally applied perturbations near an EP which has given rise to the

Title: Mechanisms of Spatiotemporal Mode-Locking [Nature Physics, arXiv, PDF] Authors: Logan G. Wright, Pavel Sidorenko, Hamed Pourbeyram, Zachary M. Ziegler, Andrei Isichenko, Boris A. Malomed, Curtis R. Menyuk, Demetrios N. Christodoulides, and Frank W. Wise Journal: Nature Physics 2020 Published on Feb 10, 2020 Abstract: Mode-locking is a process in which different modes of an optical resonator establish,

Title: Observation of the exceptional-point-enhanced Sagnac effect [Nature 576, 65–69 (2019)] Authors: Yu-Hung Lai, Yu-Kun Lu, Myoung-Gyun Suh, Zhiquan Yuan & Kerry Vahala Submitted on 4 Dec 2019. Abstract: Exceptional points (EPs) are special spectral degeneracies of non-Hermitian Hamiltonians that govern the dynamics of open systems. At an EP, two or more eigenvalues, and the

Title: Microresonator soliton dual-comb imaging [Optica 6 (9), 1110-1116 (2019), PDF] Authors: Chengying Bao, Myoung-Gyun Suh, and Kerry Vahala Submitted on 27 Aug 2019. Abstract: Fast-responding detector arrays are commonly used for imaging rapidly changing scenes. Besides array detectors, a single-pixel detector combined with a broadband optical spectrum can also be used for rapid imaging by

Title: Nonlinear Quantum Behavior of Ultrashort-Pulse Optical Parametric Oscillators (arXiv, PDF) Authors: Tatsuhiro Onodera, Edwin Ng, Niels Lörch, Atsushi Yamamura, Ryan Hamerly, Peter L. McMahon, Alireza Marandi, Hideo Mabuchi Submitted on 26 Nov 2018 Abstract: The quantum features of ultrashort-pulse optical parametric oscillators (OPOs) are theoretically investigated in the nonlinear regime near and above threshold.
