Abstract
A novel vertical coupler filter based on fused In GaAsP-InP and AlGaAs-GaAs waveguide structures is proposed and demonstrated, The large material disp ersion difference between InGaAsP and AlGaAs around 1.55 mu m and similar w aveguide geometries are used to realize a less sensitive polarization and n arrow-band filter with two separated inputs and outputs and more than -40-d B sidelobe suppression should be possible.
