Abstract
Thermo-optic 1*2 vertical coupler switches (VCSs) using a hybrid polymer/silica integration technology were designed using a finite element method and a 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 1*2 VSCs exhibiting low insertion loss, low crosstalk, low switching power, and polarization independence were demonstrated. Using this 1*2 VCS as the building block, a 1*8 VCS has been implemented.
