摘要：We have designed an air-bridged PhC microcavity with high sensitivity and a high quality *** 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 *** a thinner slab and a larger defect hole,the sensitivity is higher while the quality factor is *** the air-bridged photonic crystal slab,the sensitivity can reach 320-nm/RIU（refractive index unit） while the quality factor keeps a relatively high value of 120 by selecting the proper slab thickness and the defect hole radius,respectively,when the refractive index is *** is meaningful for low-detection-limit biosensing.
