    摘要: Illuminator module comprising VCSEL arrays with planar electrical contacts, readily adaptable for surface mounting, is provided. Monolithic VCSEL arrays are configured in array patterns on two and three-dimensional surfaces. Illuminator modules are easily expandable by increasing the array size or by modularly arranging more arrays with or without a transparent substrate. Different shapes of illuminator modules may be configured 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.

    摘要: Optical pump modules using VCSEL arrays are provided to pump optical gain media for achieving high power laser output in CW, QCW and pulse operation modes for operation. Low divergence and symmetric far-field emission from VCSELs are particularly suitable for compact arrays. VCSEL arrays configured as laser pump modules are operable at high temperatures with practically no degradation over a long period of time. VCSEL pump modules are adaptable for side- or end-pumping configurations to pump high power lasers in CW, QCW and pulse mode. Power output from VCSEL pump modules is scalable. Incorporating microlens arrays with the VCSEL arrays improve brightness of the pump modules. High power and high temperature operation of VCSEL modules make it suitable for making compact high power solid state lasers that are operable in small spaces such as, ignition of internal combustion engines, stationary power generation engines and pulsed detonation engines.
