Title:
PHOTODETECTOR
Document Type and Number:
WIPO Patent Application WO/2024/085005
Kind Code:
A1
Abstract:
A photodetector includes a wavelength separation structure including materials having different refractive indices. The materials are planarly and discretely provided for each of first pixels and second pixels on a first surface of a semiconductor substrate. The wavelength separation structure separates incident light on the first pixel into a first wavelength component and a wavelength component other than the first wavelength component and selectively guides the first wavelength component to the first pixel and separates incident light on the second pixel into a second wavelength component and a wavelength component other than the second wavelength component and selectively guides the second wavelength component to the second pixel.
