Optical switching elements using controllable defect modes in one-dimensional photonic crystals are proposed. The transmittance in a defect mode is markedly changed by modifying the local structure of the photonic crystals. Such modification is implemented by micro electro mechanical systems (MEMS) or optical manipulation. We present two methods of changing the transmittance in the defect mode. The spectral transmittance and peak wavelength in the defect mode, and the extinction ratio between on and off states are numerically analyzed using plane waves and Gaussian beams. Numerical results show that the extinction ratio is about 40 dB in 43 layers of SiO2 and air with a thickness of 6.8 μm.
