Optical isolation via direction-dependent soliton routing in birefringent soft matter

Enrique Calisto, Noel F. Smyth, Gaetano Assanto<br/>We introduce optical isolation based on reorientational solitary waves in nonuniformly oriented uniaxial soft matter, namely nematic liquid ... [Opt. Lett. 47, 2782-2785 (2022)]

Spectrum sampling optimization for quantitative phase imaging based on Kramers–Kronig relations

Yutong Li, Xiu Wen, Ming Sun, Xuyang Zhou, Yu Ji, Guancheng Huang, Keya Zhou, Shutian Liu, Zhengjun Liu<br/>Annular-illumination quantitative phase imaging based on space-domain Kramers–Kronig relations (AIKK) is a newly developed technique ... [Opt. Lett. 47, 2786-2789 (2022)]

Generation of Airy beams in Smith–Purcell radiation

Liqiao Jing, Dashuang Liao, Jie Tao, Hongsheng Chen, Zuojia Wang<br/>The metasurface has recently emerged as a powerful platform to engineer wave packets of free electron radiation at the mesoscale. Here, we ... [Opt. Lett. 47, 2790-2793 (2022)]

Thickness-dependent slow light gap solitons in three-dimensional coupled photonic crystal waveguides

Christian Bohley, Vakhtang Jandieri, Benjamin Schwager, Ramaz Khomeriki, Dominik Schulz, Daniel Erni, Douglas H.
