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.
摘要:
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.

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

Semiconductor devices in an optoelectronic integrated circuit are electrically isolated from each other by using planar lateral oxidation to oxidize a buried semiconductor layer vertically separating the semiconductor devices.
摘要:
A method for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.
摘要:
The barrier layers within a quantum well active region of a vertical cavity surface emitting laser can be silicon doped. Under thermal annealing, the silicon doped barrier layers will form disordered regions of the quantum well active region around the remaining non-disordered regions of the quantum well active region. The disordered regions of the quantum well active region will prevent diffusion of injected carriers from the non-disordered, light emitting quantum well active region.

A micro-machined movable light emitting assembly is formed on or from an undoped or pure III-V substrate or formed on or from a doped III-V substrate. The movable light emitting assemblies are to be actuated using force generators, to generate the various mechanical degrees of freedom depending on the type of stage suspension and actuation.

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.

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.
