Abstract
We introduce a photonic crystal hetero-slab-edge microcavity design with surface mode, which is beneficial for optical index sensing. The simulated index sensitivity as high as per refractive index unit (nm/RIU) variation is obtained with slab thickness of . In experiments, single surface mode lasing action from a real device is observed. Based on the surface mode in this microcavity, high experimental value of /RIU is achieved by detecting index variation in a chamber with different gas pressures.
