摘要： The present disclosure is directed toward systems for providing color-selective light detection and/or image sensing in a substantially lossless manner, thereby providing higher and up to nearly perfect optical efficiency. Embodiments disclosed herein include a plurality of pixel-repeat units, each including a color router that is configured to selectively route photons of each wavelength signal in a light signal to a different photodetector of the pixel-repeat unit. In some embodiments, the color router also functions as an anti-reflection coating that mitigates reflection of incident light, as well as a lensing system that directs substantially all photons of each wavelength signal only to their corresponding photodetector. As a result, the photodetectors collect more light than possible using prior-art absorptive color filters, thereby enabling smaller photodetectors to be used. Therefore, scaling of image sensor photodetectors to sub-wavelength sizes is possible.
