  • Fabrication of scanning III-V compound light emitters integrated with Si-based actuators
    Patent number: 6054335
    Abstract: A III-V compound light emitter is integrated with Si-based actuators. The Proposed devices take advantage of the superior optical properties of III-V compounds and the superior mechanical properties of Si, as well as mature fabrication technologies of Si-Micro-Electro-Mechanical Systems (MEMS). The emitter can be a light emitting diode (LED), a vertical cavity surface emitting laser (VCSEL) or an edge emitting laser. Electro or magnetic based actuation from Si-based actuators provides linear or angular movement of the light emitter.

  • Method and apparatus for an integrated laser beam scanner using a carrier substrate
    Patent number: 6014240
    Abstract: An solid state scanning system having a single crystal silicon deflection mirror and scanning mirror is integrated with a light source. Separation of the micro-electro-mechanical systems and light emitters on separate substrates allows the use of flip-chip and solder bump bonding techniques for mounting of the light sources. The separate substrates are subsequently full wafer bonded together to create an integrated solid state scanning system.

  • Method and apparatus for an integrated laser beam scanner
    Patent number: 6002507
    Abstract: A solid state laser beam scanning system having a single crystal silicon deflection and scanning mirror integrated with a laser diode. By combining the techniques of deep reactive ion etching of silicon with solder bump bonding techniques, completed and tested laser diodes are integrated with silicon substrates supporting micro-electro-mechanical systems layers.

  • Red and blue stacked laser diode array by wafer fusion
    Patent number: 5920766
    Abstract: A red laser structure has an inverted or p-side down orientation. The red laser structure is inverted and wafer fused to a blue laser structure to form a red/blue monolithic integrated laser structure. The top semiconductor layer of the inverted red laser structure is a GaInP fusion bonding layer which will be wafer fused to the top semiconductor layer of the blue laser structure which is a GaN cladding/contact layer.

  • Method of manufacturing vertical cavity surface emitting semiconductor lasers using intermixing and oxidation
    Patent number: 5915165
    Abstract: The present invention relates to a vertical cavity surface emitting laser with an accurately defined and controlled aperture which directs the current path within the laser. Specifically, the oxide regions surrounding the aperture are formed by a pre-oxidation layer disordering process which controls the regions within which oxidation can occur. The present invention allows for the manufacture of highly compact lasers with reproducible optical and electrical characteristics.

  • Edge-emitting semiconductor lasers
    Patent number: 5886370
    Abstract: The present invention relates to a laser with accurately defined and controlled oxide regions which provide electrical and optical confinement to the laser. Specifically, the oxide regions are formed by a pre-oxidation layer disordering process which defines the regions within which oxidation can occur. The present invention allows for the manufacture of highly compact lasers with reproducible optical and electrical characteristics.
