Abstract: A surface-emitting laser system includes a laser that emits a vertically divergent beam generally parallel to the substrate on which it is formed, and a turning mirror in the path of the beam that extends up from the substrate to a level well above the laser height. The extended mirror area reflects a greater portion of the beam than prior planar designs, increasing the output efficiency and providing a smoother beam pattern. One fabrication method employs a masking and ion beam milling technique that uses an accumulation of redeposited material to form the additional mirror area, with a thick mask layer that is later removed guiding the redeposition. An alternate fabrication method involves epitaxial growth of an additional layer of material above the conventional laser epilayers, with the additional layer subsequently removed from the laser region but retained in the mirror region.

Abstract: Optical bond-wire interconnections between microelectronic chips, wherein optical wires are bonded onto microelectronic chips. Such optical connections offer numerous advantages compared to traditional electrical connections. Among other things, these interconnections are insensitive to electromagnetic interference and need not be located at the edges of a chip but rather can be placed for optimal utility to the circuit function. In addition, such interconnections can be given the same or other pre-specified lengths regardless of the placement in the module and they are capable of signal bandwidths up to 20 Gigahertz without causing a cross-talk problem. A method of fabrication of such optical interconnections using optical fiber, a laser or photodetector and etched mirror and etched V-shaped grooves.

Abstract: A frequency synthesizer for generating a multiple tone lightwave signal that can be converted into an RF carrier or local oscillator signal. The frequency synthesizer comprises a multiple mode master laser, two slave lasers injection-locked to the master laser, an optical coupler coupling the optical outputs of the two slave lasers, which produces an optical heterodyne output. The frequency synthesizer further comprises a homodyne phase-lock loop providing feedback control over one of the slave lasers and a heterodyne phase-lock loop providing feedback control over the other slave laser. A local oscillator selector is used to select the optical mode to which one of the slave lasers is locked, thus providing selection of the frequencies of the heterodyne output.
