Patent ID: 10295765

Abstract:
A photodiode package is disclosed that includes a TO-Can style body with an exposed sensor cavity that eliminates the necessity of an encapsulant dispensing process. The TO-Can body of the photodiode package includes an integrated coupling member to allow for coupling to a ROSA housing without an intermediate member. The photodiode package includes a base portion with a cylindrical wall portion that extends therefrom to form an optical coupling cavity. A surface of the base portion provides at least one mounting surface within the optical coupling cavity for coupling to a photodiode chip. The cylindrical wall may function as an integrated coupling member and may be used to directly couple the photodiode package, e.g., without an intermediate cap/ring, into a socket of a ROSA housing. The base portion and cylindrical wall may be formed from a single piece of material, or from multiple pieces depending on a desired configuration.
