Patent ID: 7336905

Claim:
A bidirectional optical transceiver comprising: an optical fiber which is adapted to input/output optical signals and has a slant surface polished with an angle; a substrate having a groove formed on its upper surface to position the optical fiber therein in a first longitudinal portion along an optical axis; a TO-Can having a laser diode, the TO-Can being positioned opposite to the optical fiber to transmit optical signals through a second longitudinal portion of the groove to the optical fiber in a first direction; a wavelength distributor filter inserted completely into the substrate, within a slot formed on the upper surface of the substrate, and in the angle substantially matching the angle on the slant surface of the optical fiber to receive optical signals from the optical fiber in a second direction, wherein the slot is substantially orthogonal to the groove; a photodiode being positioned on the upper surface of the substrate and being configured to cover an opening of the slot, and being configured to receive optical signals from the second direction that are vertically reflected from the wavelength distributor filter; and a single housing adapted to mount the optical fiber, the substrate, and the TO-Can thereon.
