Abstract
A package includes an electronic die, a photonic die underlying and electronically communicating with the electronic die, a lens disposed on the electronic die, and a prism structure disposed on the lens and optically coupled to the photonic die. The prism structure includes first and second polymer layers, the first polymer layer includes a first curved surface concaving toward the photonic die, the second polymer layer embedded in the first polymer layer includes a second curved surface substantially conforming to the first curved surface, and an outer sidewall of the second polymer layer substantially aligned with an outer sidewall of the first polymer layer.
