Abstract
Some embodiments relate to an integrated circuit (IC) device that includes a first substrate including an optical lens at a frontside surface of the first substrate, an electrical IC structure disposed proximate a backside surface of the first substrate, and a photonic IC structure disposed proximate a backside surface of the electrical IC structure. The photonic IC structure includes a second substrate providing a backside surface of the photonic IC structure; a photodetector, a grating coupler, and an inverse grating coupler disposed over a frontside surface of the second substrate; and a reflector disposed at a frontside surface of the photonic IC structure. The grating coupler and the inverse grating coupler are configured to direct light from the optical lens and the backside surface of the second substrate, respectively, to the photodetector. The reflector is configured to direct light from the inverse grating coupler back to the inverse grating coupler.
