Abstract: VCSEL arrays with planar electrical contacts readily adaptable for surface mounting are provided. Monolithic VCSEL arrays are configured in array patterns on two and three-dimensional surfaces for configuring optical illuminator modules. Illuminator modules are easily expandable by increasing the array size or by modularly arranging more arrays with or without a transparent substrate, in different shapes by tiling array modules monolithically on a common substrate, or by tiling small modules. The surface mountable illuminator modules are easily assembled on a thermally conductive surface that may be air or liquid cooled for efficient heat dissipation. Array modules may be integrated with other electronic circuits such as current drivers, sensors, controllers, processors, etc. on a common platform, for example, a single or multiple layer printed circuit boards (PCB) to assemble illumination systems for different applications including a gesture recognition apparatus and a battery operated portable illuminator devices.

Abstract: A structured light source comprising VCSEL arrays is configured in many different ways to project a structured illumination pattern into a region for 3 dimensional imaging and gesture recognition applications. One aspect of the invention describes methods to construct densely and ultra-densely packed VCSEL arrays with to produce high resolution structured illumination pattern. VCSEL arrays configured in many different regular and non-regular arrays together with techniques for producing addressable structured light source are extremely suited for generating structured illumination patterns in a programmed manner to combine steady state and time-dependent detection and imaging for better accuracy. Structured illumination patterns can be generated in customized shapes by incorporating differently shaped current confining apertures in VCSEL devices. Surface mounting capability of densely and ultra-densely packed VCSEL arrays are compatible for constructing compact on-board 3-D imaging and gesture recognition systems.

Abstract: A set of VCSEL fabrication methods has been invented which enhance the performance and long time reliability of VCSEL devices and arrays of devices. Wafer bow caused by growing a large number of epitaxial layers required to fabricate VCSEL device generates strain and results in bowing/warping of the device wafer. The stress so generated is eliminated by applying a stress compensation layer on the substrate to a surface opposite to the epitaxial layer surface. New oxidation equipment designs and process parameters are described which produce more precision apertures and reduce stress in the VCSEL device. An ultrathin fabrication procedure is described which enables high power VCSELs to be made for high power operation at many different wavelengths. A low temperature electrical contacting process improves VCSEL long term reliability.

Abstract: Touch screen sensor systems that incorporate VCSELs or VCSEL arrays to provide illumination beams for sensing the position of objects such as a finger or stylus in a two dimensional space is provided. Normally the touch sensor is used with a display screen so that objects in the display screen are identified by positioning a finger or stylus at the object's position. The invention describes improved illumination methods using VCSELs that realize higher resolution in position sensing. VCSELs can also be integrated with detectors on a common substrate which provides both illumination and detection functions for the touch sensor system. Different methods to suitably couple light from VCSEL arrays directly, or through guided light paths such as fibers and waveguide arrays are provided to configure a touch sensor in different applications.

Abstract: A high efficiency optical ignition device is provided in a two-part compact and robust package to be mounted directly on an internal combustion engine chamber. The ignition device ignites a combustion fuel with a high intensity plasma generated by a high power laser beam from a solid state laser operable in Q-switched, or non-Q-switched mode for producing short or long pulses, respectively. Multiple pulses are generated, and duration and frequency of the laser beam pulses are controlled by controlling an optical pump module to pump the solid state laser. The optical pump module comprises a semiconductor laser, preferably a VCSEL device. One or more laser beams are precisely directed, each one to a desired location anywhere within the combustion chamber for more efficient and near complete burning of the combustion fuel. The robust packaging is well suited to withstand mechanical and thermal stresses of the internal combustion engine.

Abstract: A miniature structured light illuminator is provided. The miniature structured light illuminator uses a semiconductor surface emitting array including VCSEL or RC-LED array and an array of microlens elements to generate a wide range of structured light illumination patterns. The emission beam from a surface emitter array may be selectively directed, steered, focused or expanded, by applying a lateral displacement of the microlens array, such that centers of the emission beam and microlens array are misaligned. Emitted beams may be directed through small optical components to project the structured light pattern to a distant plane. The surface emitting arrays may be configured in addressable form to be activated separately for continuous or pulsed operation with very fast pulses having
