Microwave Photonics Enhanced Microresonator Sensors

Abstract

Optical microresonators (OMRs), which can be used as compact and highly sensitive optical sensors, are considered to be an ideal platform for optical sensing. However, the resolution of conventional optical interrogation sensing is limited by the challenges of the fabrication process and the limited resolution of optical instruments. Recently, the microwave photonic (MWP) has attracted attention due to its high-resolution sensing application. Various high-speed and high-resolution sensors based on OMR and MWP have been demonstrated, which shows the great potential of OMR-based MWP sensing in high-demand sensing scenarios. This thesis presents a detailed analysis of integrating MWP techniques with OMR sensors on a silicon-on-insulator platform.
