Abstract

A silicon waveguide in an electro-optic (EO) polymer cladding-based directional coupler switch was designed and fabricated. Optimal dimensions for efficient coupling and minimal crosstalk are found analytically (coupled mode theory) and numerically for 1550nm wavelength. Both coplanar electrode spacing and height are taken into account for most effective poling conditions and performance. The design consists of two 255nm wide waveguides separated by 500nm and is optimized for TE propagation. With an electrode separation of 4μm and coupling length of 1.7cm, a switching voltage (Vs) < 10V at an r33 of 250pm/V is expected.
