Scatterer assisted whispering gallery mode microprobe
Fangjie Shu, Xuefeng Jiang, Guangming Zhao +1
Fiber based whispering-gallery-mode (WGM) microprobe, combining both the high optical field enhancement of the WGMs and the practicability of the fiber probe, is highly demanded in…
Chiral Symmetry Breaking in Micro-Ring Optical Cavity By Engineered Dissipation
Fang-Jie Shu, Chang-Ling Zou, Xu-Bo Zou +1
We propose a method to break the chiral symmetry of light in traveling wave resonators by coupling the optical modes to a lossy channel. Through the engineered dissipation, an indi…
Transient Microcavity Sensor
Fang-Jie Shu, Chang-Ling Zou, Şahin Kaya Özdemir +2
A transient and high sensitivity sensor based on high-Q microcavity is proposed and studied theoretically. There are two ways to realize the transient sensor: monitor the spectrum…
Extremely local electric field enhancement and light confinement in dielectric waveguide
Qijing Lu, Fang-Jie Shu, Chang-Ling Zou
The extremely local electric field enhancement and light confinement is demonstrated in dielectric waveguide with corner and gap geometry. The numerical results reveal the local el…
Dielectric Bow-tie Nanocavity
Qijing Lu, Fang-Jie Shu, Chang-Ling Zou
We propose a novel dielectric bow-tie nanocavity consisting of two tip-to-tip opposite triangle semiconductor nanowires, whose end faces are coated by silver nanofilms. Based on th…
Ultralong distance coupling between asymmetric resonant microcavities
Fang-Jie Shu, Chang-Ling Zou, Wen-Cong Chen +1
The ultralong distance coupling between two Asymmetric Resonant Microcavities (ARCs) is studied. Different from traditional short distance tunneling coupling between microcavities,…
An Optimization Method of Asymmetric Resonant Cavities for Unidirectional Emission
Fang-Jie Shu, Chang-Ling Zou, Fang-Wen Sun
In this paper, we studied the repeatability and accuracy of the ray simulation for one kind of Asymmetric Resonant Cavities (ARCs) Half-Quadrupole-Half-Circle shaped cavity, and co…
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…
Collimated directional emission from a peanut-shaped microresonator
Fang-Jie Shu, Chang-Ling Zou, Fang-Wen Sun +1
Collimated directional emission is essentially required an asymmetric resonant cavity. In this paper, we theoretically investigate a type of peanut-shaped microcavity which can sup…
