Patent ID: 8203115

Claim:
An integrated hyperspectral imager comprising: a planar photonic substrate; and a plurality of imaging pixel photonic circuits disposed in a M×N array on said planar photonic substrate, each imaging pixel photonic circuit comprising: an input coupler configured to receive a broadband input electromagnetic radiation; a waveguide optically coupled to said input coupler; a plurality of wavelength filters optically coupled to said waveguide, each wavelength filter of said plurality of wavelength filters having a wavelength filter input and a wavelength filter output; and a plurality of detectors, each detector of said plurality of detectors having a detector input optically coupled respectively to each of said wavelength filter outputs, each detector of said plurality of detectors having a respective detector output; said integrated hyperspectral imager configured to provide at said detector outputs of each of said plurality of imaging pixel photonic circuits electrical signals representative of a hyperspectral image of said received broadband input electromagnetic radiation.
