2x2 waveguide based thermooptic photonic switch

Abstract

We demonstrate a waveguide based thermooptic photonic switch with low electric power consumption using polymer material. The buried square core waveguides structure has been adopted for single mode operation at third telecommunication window. The index contrast of the upper cladding and the waveguiding layers is 0.2%, the lateral section of the waveguiding and lower cladding layer is 0.35%. The asymmetrical fabricated switch exhibits very low switching power of 12.26 mW. The crosstalk level of -30 dB for the initial and switching states have been achieved, respectively.
