Abstract
A twodimensional photonic crystal crosswaveguide 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 crosswaveguide can be used as a high performance dualchannel stress sensing device based on tunable photonic crystal structureSupported by the National Natural Science Foundation of China under Grant No 51404268 the Foundation Research Project of Jiangsu Province of China The Natural Science Fund under Grant No BK20130206 the Specialized Research Fund for the Doctoral Program of Higher Education of China under Grant No 20130095120020
