Research on Characteristics of Broadband Acoustic Sensor Based on Silicon-Based Grooved Microring Resonator
In order to meet the requirements of having a small structure, a wide frequency band, and high sensitivity for acoustic signal measurement, an acoustic sensor based on a silicon-based grooved microring resonator is proposed. In this paper, the effective refractive index method and the finite element...
