Abstract

We interpret the modified bifurcation optically active waveguide switch structure for a polymeric electrooptic (EO) 2×2 switch. PEI-DR1, UFC150, and Resole HM2 were used as the core EO material, the lower clad material, and the upper clad material, respectively. We present the optical and electrical properties on this material system for high-performance devices. We fabricate the electrically and optically packaged polymeric EO 2×2 switch for high-speed optical communications. At an operating voltage of 8.5 V, the crosstalk of the cross-arm is -18.1 dB, and that of the straight arm is -18.5 dB. The measured optical loss is 14 dB at λ=1.3 μm. The 6-dB attenuation in radio-frequency transmission corresponds to about 17 GHz
