Abstract
This paper reports the theoretical investigation of the strain sensitive effect of a 2D photonic crystal (PhC) nanocavity resonator for mechanical sensing applications. By using finite element method (FEM) using ANSYS software and finite different time domain (FDTD) simulation using CrystalWave software, the strain sensitivity of high quality factor PhC nanocavity have been studied. Linear relationships between strain and shift of resonant wavelength of the cavity have been obtained. The sensitivities to longitudinal and transverse strains have been determined to be 1.67nm/mε and 1.4nm/mε, respectively.
