Abstract
An optical filter has at least one input waveguide, a wavelength dispersive device receiving light from the optical input, and an optical output having a plurality of spatially separated waveguides receiving respective wavelength bands of light from the wavelength dispersive device, at least one of the waveguides in the optical output or optical input forming part of an evanescent waveguide coupler comprising a group of coupled waveguides side by side.
