Passive alignment members for surface emitting and detecting optoelectronic devices having a silicon substrate with a front surface and a back surface and a selected thickness therebetween; side surfaces with holes having vertical registration surfaces etched therein for receiving alignment pins; and at least one optoelectronic device disposed on the front surface, the device being aligned to the hole.

Passive alignment member for vertical surface emitting/detecting device

A technique for passive alignment of an opto-electronic device, such as laser, by alignment fiducials to a silicon wafer board utilizes a tilted notch in the opto-electronic device. This system overcomes limitations using standard etched notches for previous passive alignment systems. Specifically, the tilted notch presents a range of offset distances between the edge of the notch and the active light-emitting spot of the laser. Depending on the location at which the wafer is diced or cleaved, the distance from the notch on the laser to the laser stripe can be adjusted after the laser wafer is fabricated.

An optical bidirectional link comprising: a module having a lower surface and an upper surface. The upper surface having disposed thereon a submodule having an optical transmitter and detector mounted thereon. Circuitry mounted on the upper surface. The circuitry having electronic components for effecting bidirectional communication via the optical transmitter and detector. A cover disposed over the upper surface of the module, wherein the submodule further comprises a silicon substrate having an optical fiber disposed in v-groove, a laser, reflective surfaces, and a holographic plate disposed on an upper surface of the silicon substrate.

Bidirectional link submodule with holographic beamsplitter

An apparatus for coupling an optical fiber to an optical device comprises a substrate and a passive alignment member. The substrate having a top surface and a bottom surface. The top surface having a fist groove disposed thereon for holding an optical fiber, and a second groove disposed on the top surface. The second groove being substantially orthogonal to the first groove. The passive alignment member disposed in the second groove. The passive alignment member having selectively etched forward and side pedestals for aligning the optical device to the optical fiber disposed in the first groove.
