| 摘 要： | We have designed an air-bridged PhC microcavity with high sensitivity and a high quality factor.The structure parameters of the microcavity are optimized by three-dimensional finite-difference time-domain method. We compare the performance of a silicon-on-insulator PhC microcavity and an air-bridged PhC microcavity,and analyze the effect of the thickness of the slab and the radius of the defect hole on the performance of the air-bridged PhC microcavity.For a thinner slab and a larger defect hole,the sens...
