Abstract： 

　　An optical microcavity is an optical resonator with the size in the order of wavelength of the light. Due to the advantages of high quality factor, samll mode volume and large flexibility, different microcavities are recently intensively studied in various applications, including cavity quantum electrodynamics, nonlinear optical effects, optical signal processing, light emission and sensing. In our research, we focus on the planar microcavities on silicon platform, which is compatible with standard Si process technology and is integratable on single Si chip. In this report, we will introduce the high-resolution processing technology for Si microcavities, then introduce its applications in optical bi-stability, optical diode, Si-based light-emitting devices based on Ge self-assembled quantum dots, and single Ge quantum dot precisely embedded in photonic crystal nanocavity.
