Abstract

For the first time a narrowband wavelength filter in InGaAlAs-’ InP is reported. A highly asymmetrical, vertically-coupled directional coupler operating near the band edge is formed by a narrow ridge and a wide strip-loaded waveguide. Operation at a centre wavelength of ~1.5μm with a bandwidth of ISA and transfer efficiency of ~50-70% has been achieved.
