High performance 2 × 2 polymeric electro-opticswitch with modified bifurcation optically active waveguide structure

A polymeric 2 × 2 electro-optic switch has been fabricated using the modified bifurcation optically active type of waveguide, which consists of two multimode regions and a phase controlling region. This structure is insensitive to processing environment, unlike conventional 2 × 2 structures. The operating voltage is 10 V with an electrode length of 12 mm, and crosstalk is ~–18 dB.
