Abstract:
Provided is a spectral sensor array, including: a planar waveguide on a substrate; a chirped input coupling grating, wherein the chirped input coupling grating comprises a transverse chirp to provide a spectrally selective coupling of incident light into the planar waveguide; an output coupling grating; and an array of photodetectors arranged to receive the light coupled out of the waveguide.
