A novel optical switch based on silicon/kaolinite photonic-crystal line-defect waveguides is proposed. The optical switch is analyzed and simulated with the finite-difference time-domain (FDTD) method. The designed optic switch operates with high extinction ratio of 40 dB, and compact size of 10 Mm at 1550 nm wavelength. Being a compact in size and silicon base photonic crystal, the device is very suitable for high-density integrated optics circuits.
