Adiabatic embedment of nanomechanical resonators in photonic microring cavities
Chi Xiong, Wolfram Pernice, Mo Li +2
We report a circuit cavity optomechanical system in which a nanomechanical resonator is adiabatically embedded inside an optical ring resonator with ultralow transition loss. The n…
High performance nanophotonic circuits based on partially buried horizontal slot waveguides
Chi Xiong, Wolfram H. P. Pernice, Mo Li +1
We present a novel platform to construct high-performance nanophotonic devices in low refractive index dielectric films at telecoms wavelengths. The formation of horizontal slots b…
