Abstract:

In terms of photoelastic effect of the medium, the band characteristics of two-dimensional (2D) photonic crystals were analyzed by finite element method. The photoelastic effect of the medium composing 2D photonic crystals cause change of its refractive index when imposed by stress, the band structure of 2D photonic crystals varies accordingly. The effect of stress on the structural characteristics of band gap in 2D Si/SiO2 photonic crystals was analyzed in detail. And for each band gap, the variation of start wavelength, cut-off wavelength and bandwidth is proportional to stress.

Key words: o optoelectronics, band characteristics, finite element method, two-dimensional photonic crystals, photoelastic effect, stress
