Absence of universal backscattering immunity in reciprocal photonic waveguides
Yecheng Hu, Ming Gao, Wei Xie +6
Suppressing parasitic back-reflection caused by imperfections, such as random defects, material inhomogeneities, localized inclusions, and fabrication-induced geometric deviations,…
Inverse-Designed Metasurfaces for Compact Optical Skyrmion Generation with High Topological Fidelity
Donghyun Park, Alex Song, Haejun Chung +1
Optical skyrmions are structured vector fields with nontrivial polarization topology and subwavelength-scale features. One common approach to generating optical skyrmions is the su…
Asymptotic stability of laser-driven lightsails: Enhancement by optical dispersion engineering in gratings
Jadon Y. Lin, Liam van Ravenstein, C. Martijn de Sterke +3
Lightsails are promising spacecraft that can traverse interstellar distances within decades via radiation-pressure propulsion from high-power lasers. The envisioned missions crucia…
Counter-propagating Entangled Photon Pairs from a Monolayer
Zhuoyuan Lu, Jiri Janousek, Syed M. Assad +9
Non-phase-matched spontaneous parametric down-conversion (SPDC) in atomically thin materials provides new degrees of freedom and enhanced quantum information capacity compared to c…
All-optical damping forces enhanced by metasurfaces for stable relativistic lightsail propulsion
Jadon Y. Lin, C. Martijn de Sterke, Michael S. Wheatland +2
Lightsails are a promising spacecraft concept that can reach relativistic speeds via propulsion by laser light, allowing travel to nearby stars within a human lifetime. The success…
