查询词典 switch

A novel design scheme for digital optical switch with high extinction ratio by employing S curve waveguide at the end of the Y branch ii proposed. Higher extinction ratio then that of the device without S curve waveguide is obtained by applying certain synchronous voltage to tie Y branch and the curve electrode of tie S curve waveguide.
