Abstract: 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 H1, the light-receiving surface is separated from the topmost surface by a second distance H2, and H1 is different from H2.
