1. An optical sensing device, comprising:
a carrier body having a topmost surface and a bottommost 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;
wherein the first light-emitting device and the light-receiving device are completely located within a space sandwiched by the topmost surface and the bottommost surface, the light-emitting surface is vertically separated from the topmost surface by a first distance H1, the light-receiving surface is vertically separated from the topmost surface by a second distance H2, and H1 is different from H2.
