Patent ID: 7409124

Claim:
A fiber waveguide optical subassembly, comprising: a light emitter, for emitting an output light signal; a first optical transmission element having a front end and a relative rear end, and a ball lens located between said light emitter and said front end of said first optical transmission element, said front end coupling with said light emitter for receiving and transmitting said output light signal; a splitter, located on said rear end of said first optical transmission element for said output light signal passing through; a second optical transmission element, located on one side of said splitter, for passing said output light signal and receiving an input optical signal; a light detector, located aside said splitter for receiving said input optical signal transmitted through said second optical transmission element and reflected by said splitter; a monitor, adjacent to said light emitter; and an optical bench for carrying said light emitter, said first optical transmission element, said splitter; said second optical transmission element said light detector and said monitor, said optical bench comprising an emitter carrier for carrying and fixing said light emitter onto said optical bench, said emitter carrier further comprising a reflective surface for reflecting said output light signal to said monitor; wherein said optical bench has bench grooves positioning said first optical transmission element and said second optical transmission element, a splitter groove positioning said splitter and an emitter groove positioning said light emitter, said bench grooves and said splitter groove and said emitter groove being integrally formed at a same surface of said optical bench.
