Document Type and Number:
WIPO Patent Application WO/2023/161971
Kind Code:
A1
Abstract:
A waveguide-type light receiving element (10) according to the present invention is provided with: a semi-insulating semiconductor substrate (11); a light absorption layer (12) which is formed on one main surface of the semiconductor substrate (10) and has a pair of bonding surfaces that are perpendicular to the one main surface of the semiconductor substrate (10) and an incident end face (12A) on which light is incident and which has end sides of the pair of bonding surfaces, the end sides facing each other, as a pair of opposite sides thereof, with the layer thickness of the incident end face being larger than the layer width of the incident end face; an n-type semiconductor layer (13) which is joined to one of the pair of bonding surfaces of the light absorption layer (12) on the one main surface of the semiconductor substrate (11); and a p-type semiconductor layer (14) which is joined to the other one of the pair of bonding surfaces of the light absorption layer (12) on the one main surface of the semiconductor substrate (11).
