Abstract
A pixel structure having a cladding and tapered core waveguide, the core dimensioned to refract EM radiation through the cladding at differing depth dependent on the wavelength of the radiation, and a plurality of detectors disposed to convert the band of radiation they receive into electrical signals. In some embodiments the detectors are disposed within lateral waveguides, and in some embodiments below the tapered core waveguide. Further disclosed is an image array sensor comprising a plurality of such pixel structures. Further disclosed is an array comprising stacked layered waveguides having detectors disposed therewithin, and a plurality of refractors to refract different bands of EM radiation into differing waveguides.
