Abstract
Official abstract text for this publication.
Provided is a solid-state imaging device capable of ranging with high precision even when the pixel size is small. The solid-state imaging device includes: an optical waveguide having multiple regions with different refractive indices; and a photoelectric conversion unit for converting light guided through the optical waveguide into an electrical signal. The optical waveguide includes a main waveguide located on a light incident side, and a first sub waveguide and a second sub waveguide connected to the main waveguide and located on the photoelectric conversion unit side. The main waveguide guides light which enters from a first direction and light which enters from a second direction. The first sub waveguide and the second sub waveguide guide light which has entered from the first direction and has passed through the main waveguide and light which has entered from the second direction and has passed through the main waveguide, respectively.
