摘要
A Nano-opto-mechanical pressure sensor using optical force is reported in this paper. The pressure sensor consists of a square diaphragm, a ring resonator and four waveguides. By applying a pressure ranging from 900 kPa to 990 kPa, the output intensity ratio sensitivity of 2.272 /kPa is achieved. Compared with traditional MEMS pressure sensor, the proposed ring pressure sensor has advantages such as higher sensitivity and resolution, which could be applied to acoustic pressure sensors and microphones etc.
