摘要： A photodetection device comprises: an image sensor that includes first pixels, second pixels, third pixels, and fourth pixels; an interference element that includes first incident regions and second incident regions; and an optical system that causes light in a first wavelength band to be incident on the first incident regions and causes light in a second wavelength band different from the first wavelength band to be incident on the second incident regions. The interference element causes first interference of part of the light in the first wavelength band incident on two first incident regions that are included in the first incident regions. The interference element also causes second interference of part of the light in the second wavelength band incident on two second incident regions.

摘要： Embodiments of the present disclosure provide systems and methods for providing integrated waveguide-based spectrometer systems. In one aspect, the system includes an optical spectrometer comprising one or more waveguides configured to support propagation of optical radiation (i.e. light) through the waveguides to a photodetector. The spectrometer further includes an input coupler for each waveguide, the input coupler configured to couple the radiation from free space into the waveguide in absence of fiber-optic coupling of the radiation into the waveguide. Because at least a portion of the light propagated through the waveguides has interacted with a sample to be spectroscopically evaluated, the light detected by the photodetector allows to carry out the spectroscopic evaluation of the sample. At least some components of the spectrometer are provided on a single die using conventional CMOS techniques, yielding a compact and low cost device.
