Patent ID: 7260328

Claim:
An optoelectronic assembly for multiplexing and/or demultiplexing optical signals, comprising: a monolithic multiplexing member for multiplexing and/or demultiplexing optical signals, wherein said multiplexing member has opposing parallel and substantially planar surfaces; a first optical imaging system for coupling light beams having light of multiple combined frequencies between an optical channel and said multiplexing member; a second optical imaging system for coupling light beams each having one wavelength with said multiplexing member; said first optical imaging system being integrated into a single-channel interface member and said second optical imaging system being integrated into a multi-channel interface member, said interface members being connected directly to said multiplexing member, wherein the interface members are disposed on opposite surfaces of the opposing parallel substantially planar surfaces of said multiplexing member; at least one optical element; an optically transparent sealing compound optically coupling directly said multi-channel interface member to said at least one optical element and containing an optical path between said multi-channel interface member and said at least one optical element; and said interface members being constructed as unipartite shaped pieces.
