Abstract
A spectral sensor and a method for forming the spectral sensor is disclosed. The spectral sensor includes a planar waveguide on a substrate; a restriction mechanism that restricts a range of angles of incidence of light impinging onto the chirped input coupling grating; the chirped input grating formed to couple incident light into the planar waveguide, wherein the chirped input coupling grating comprises a first transverse chirp to provide a spectrally selective coupling of incident light Into the planar waveguide; a propagation region to filter out light that is not coupled into the planar waveguide; a detector array arranged on the opposite side of the propagation region from the chirped input coupling S grating to receive light coupled out of the planar waveguide and produce output signals representative of the light; and an electrical circuit to readout output signals from the detector array.
