Thermo-optic 1x2 vertical coupler switches (VCSs) using a hybrid polymer/silica integration technology were designed using finite element method and coupled mode method for different refractive index contrasts. The multilayer structures were optimized by thermal analysis. Based on this design and simulation, hybrid polymer/silica thermo-optic 1x2VSCs exhibiting low insertion loss, low crosstalk, low switching power, and polarization independence were demonstrated. Using this 1x2VCS as the building block, a 1x8VCS has been implemented.

Since the realization of first polymer channel waveguides in the early 70ths and the market introduction of polymer fibres research work is aiming to increase the integration level of photonic circuits. This paper reports the state of the art in passive and active polymeric integrated optics in view of the requirements for practical applications in telecom and data processing systems.
