Abstract :
A TE-Optical switch based on transmission properties in square-lattice photonic crystals with a unit cell made of a rotated square cylinder and four horizontal thin plates and a modified one in which tubes filled with air are used instead of thin plates are investigated. The bandgaps are modified when the thin plates are replaced by the tubes, leading to the TE-optical switch function. The switch has been designed and studied by the plane-wave and finite-difference time-domain simulations. For the TE-optical switch, the extinction coefficients reach to -17dB, -30dB, and -38dB, respectively. The proposed optical switch is good for optical integrated circuits.
