This disclosure discloses an optical sensing device. The device includes a carrier body having a topmost surface; a first light-emitting device disposed on the carrier body and having a light-emitting surface; and a light-receiving device comprising a group III-V semiconductor material disposed on the carrier body and having a light-receiving surface. The light-emitting surface is separated from the topmost surface by first distant H, the light-receiving surface is separated from the topmost surface by a second distance H, and His different from H

Optical sensing device and optical sensing system thereof comprising light emitting device and light receiving device completely sandwiched by the topmost surface and bottommost surface of a carrier body with different vertically separated distances

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 &#x2265;13.
