Abstract

In this paper, we have presented the design of resonator structure in photonic crystals to improve two parameters i.e., Quality Factor and Sensitivity. Photonic Crystal based force sensor includes hexagonal rings in 2-D Photonic Crystal silicon slab of hexagonal lattice which are to be integrated on the top of Silicon Microcantilever for Sensing applications. Ring resonator has been arranged in between two silicon Photonic Crystals waveguides, i.e., bus and drop waveguides. The new ring-resonators has formed by removing the holes of a hexagonal lattice from two-dimensional silicon Photonic Crystals slab. The parameters Quality Factor and Sensitivity can be improved by tuning the size of holes in the hexagonal resonator structure. 2-D Finite Difference Time Domain Method and Finite Element Method has been used for simulation.
