Abstract:
There is provided a light receiving device including a polarization dispersing section that disperses a polarization direction of incoming light into a plurality of polarization directions, a light collecting section that has a metal pattern shaped like concentric circles on a surface thereof, where the light collecting section collects light that has passed through the polarization dispersing section, and a light receiving section that receives the light collected by the light collecting section. Also provided are a light receiving device manufacturing method and a light receiving method. The light collecting section may have a surface plasmon antenna that has the metal pattern shaped like the concentric circles on a surface thereof, and the light receiving section may receive the light collected toward a center of the concentric circles of the metal pattern of the light collecting section, through a hole at the center of the concentric circles, on a rear side of the light collecting section.
