This paper reports the theoretical and experimental investigations of the strain-induced resonant wavelength shift effect of a 2-D photonic crystal (PhC) cavity for strain sensing applications. Strain sensitivity of a high quality factor PhC cavity is studied based on finite element method (FEM) and finite difference time domain (FDTD) simulations. The results show that the resonant wavelength of cavity is proportional to the application of strain. Linear relationships between strain applied and shift of resonant wavelength were obtained. Accordingly, it is possible to detect the strain by determining resonant wavelength ...

The sensitivity to longitudinal strains was determined to be 0.95 pm/孳train.
