Abstract :
We demonstrate a novel vertical coupler structure based on wafer fusion technology that combines two different material systems: AlGaAs-GaAs with a low material dispersion at 1.55 μm and InGaAsP-InP with a high material dispersion. With a proper design, a very narrowband and polarization independent monolithic filter with separated inputs and outputs can be realized
