Dynamic process of free space excitation of asymmetry resonant microcavity
Fang-Jie Shu, Chang-Ling Zou, Fang-Wen Sun
The underlying physics and detailed dynamical processes of the free space beam excitation to the asymmetry resonant microcavity are studied numerically. Taking the well-studied qua…
Theory of free space coupling to high-Q whispering gallery modes
Chang-Ling Zou, Fang-Jie Shu, Fang-Wen Sun +3
A theoretical study of free space coupling to high-Q whispering gallery modes both in circular and deformed microcavities are presented. In the case of a circular cavity, both anal…
Doubly and triply coupled nanowire antennas
Liu Lu, Lulu Wang, Chang-Ling Zou +5
Nanoantenna is one of the most important optical components for light harvesting. In this study, we show experimental evidence of interactions between coupled nanowires by comparin…
Broadband opto-mechanical phase shifter for photonic integrated circuits
Xiang Guo, Chang-Ling Zou, Xi-Feng Ren +2
A broadband opto-mechanical phase shifter for photonic integrated circuits is proposed and numerically investigated. The structure consists of a mode-carrying waveguide and a defor…
