Abstract
This disclosure discloses an optical sensing device. The device includes a carrier body; a first light-emitting device disposed on the carrier body; and a light-receiving device including a group III-V semiconductor material disposed on the carrier body, including a light-receiving surface having an area, wherein the light-receiving device is capable of receiving a first received wavelength having a largest external quantum efficiency so the ratio of the largest external quantum efficiency to the area is ≥13.
