Contribution of Strain and Elasto-Optical Effect to Resonant Mode in the Two-Dimensional Photonic Crystals Force Sensor
The resonant wavelength of the two-dimensional photonic crystal force sensor model changing with normal stress along y direction is calculated by finite-difference time-domain method. The result shows that the variation of the size and shape of the resonant cavity has a main contribution to the variation of the resonant wavelength. The elasto-optical effect of GaAs medium can not obviously change the wavelength of the resonant cavity below score of megapascal.
