摘要：

A two-dimensional photonic crystal cross-waveguide consisting of dielectric rods array immersed in air is designed. The optical field pattern and transmission spectra are analyzed by finite difference time domain method. The propagation characteristics and stress sensing behavior of photonic crystal are emphasized through analyzing the linear shift of central wavelength. The results show that optimized cross-waveguide can be used as a high performance dual-channel stress sensing device based on tunable photonic crystal structure.
