Abstract: Methods to minimize electro-corrosion in the water cooling ports of stacked heat sinks (coolers) and components fabricated according to those methods are disclosed.
Abstract: A cooling device includes a thermally conductive object having an opening configured to receive an optical component, the opening being configured such that the optical component is thermally and optically operationally connected to the thermally conductive and electrically conductive object. One or more cooling components, microchannel coolers in one instance, are also thermally operationally connected to the thermally conductive and electrically conductive object. Methods of use are disclosed.

Abstract: Systems and methods for providing a low stress electrode connection capable of carrying a high electrical current to an edge-emitting device, such as a laser diode are described. Systems and methods for providing mechanisms to allow precise adjustment of the relative position of one heat-sink for an optical edge emitting device relative to an adjacent heat-sink in a stack of heat-sinks are also provided herein.
Abstract: A method of attaching a semiconductor component to a heat-sink where the component is first placed onto a heat-sink substrate whose attachment surface comprises a malleable-metal film, a semiconductor component is placed onto the malleable-metal film, and pressure and heat is applied for a predetermined time to the stack including substrate with malleable-metal film and semiconductor component.

Abstract: The method of these teachings includes processing a semiconductor structure forming an active waveguide of a semiconductor laser in an environment free of contamination in order to provide contamination free mirror facets at the ends of the active waveguide, and depositing a single crystal passivation layer comprised of a semiconductor whose bandgap exceeds that of the active layer and the waveguide layers and that does not form misfit dislocations with the laser diode semiconductor, the deposition occurring at a temperature at which the semiconductor structure does not degrade.
Abstract: According to the invention, an apparatus for transferring heat with a target is disclosed. The apparatus may include a body which defines a surface, inlet and outlet ports, inlet and outlet manifold passages, and heat transfer passages. The surface may couple the target with the body. The inlet port may be configured to receive and direct a fluid into inlet manifold passages. The outlet port may be configured to receive and output the fluid. The inlet and outlet manifold passages may be configured to receive and direct the fluid to and from the heat transfer passages. The heat transfer passages may be configured to receive and direct all of the fluid from the inlet manifold passages in one or more directions substantially parallel to the surface and substantially perpendicular the input manifold passages. At least one heat transfer passages may have a plurality of fins on at least one surface.
Abstract: Protection methods and protection systems, for high current semiconductor devices with diode junctions, that detect the anomalies in the local temperature at small areas of the junction and protect the device from accelerated aging and premature catastrophic damage. In an embodiment of the method of this invention for protecting a high current semiconductor devices with diode junctions, anomalies in the electrical or optical behavior of the junction are detected and, upon detection of the anomalies, power is diverted away from or around the device.
