Abstract

A new 2D PBG directional coupler switch is proposed and analyzed by the FDTD method. A 1.55-micrometers device is designed in a square lattice of silicon posts in air. The switching mechanism is a change in the conductance of posts located in the waveguide coupling region, Conductance is induced electrically by carrier injection or is induced optically by electron-hole pair generation. Low insertion loss and optical crosstalk below -23 dB in both the cross and bar switching states are predicted.
