Paper Abstract

Directional couplers with four sections poled in four perpendicular directions are proposed for the first time as a new electro-optic switch configuration in which complete conversion of both TE and TM light from one waveguide to the other can be achieved simultaneously by a low driving voltage adjustment. The perpendicularly poled sections of the switch make the device completely polarization- independent, and the inversely poled sections offer an extremely relaxed fabrication tolerance for the device. This configuration of each section poled in a different direction also makes it possible to drive the electro-optic coupler with a uniform electrode, which ensures high-speed operation of the device. Both the switching characteristics and the fabrication tolerance are simulated.
