  • Abstract
    A GaInAsP/InP waveguide narrow-band wavelength filter is proposed and analysed. The proposed wavelength filter is based on an asymmetric semiconductor directional coupler having a step-index waveguide and a double clad waveguide. It is numerically shown that a bandwidth as narrow as 5.4 nm is feasible for 1.3 mm long devices at a 1.53 mu m centre wavelength.
