Abstract

We have designed a novel Spot-Size converter (SSC) which is constructed with a tapered silicon waveguide and an overlaid rectangular sol-gel hybrid SiO₂ waveguide. Simulation analysis based on the three-dimensional beam propagation method (3D-BPM) shows the conversion efficiency can be up to 95% (loss of 0.22 dB).
