    摘要: The use of one or more angled or curved and diverging light pipes or reflectors placed in a light source's, e.g. diode's, emission path at appropriate distances, angles and divergence, such that a diode's emission spot size is modified and or redirected from the diode's natural emission path to alternative planes at angle to the diode's natural emission path so that a diode emission safe spot size can be achieved on any plane at angle to the original diode natural emission path at minimum distances from the diode's point of emission.

    摘要: A reflector is mounted to an outer perimeter of a heat sink holding at least one edge-emitting semiconductor chip, for example a laser diode. The reflector has a shape suitable for gathering light emitted by the laser diodes and redirecting the light in an upward direction away from the heat sink. The reflector can be overmolded onto the heat sink. The reflector can operate by total internal reflection, so that no additional reflector coating step is required. Injection molding of the reflectors onto the heat sink holding the laser diodes enables mass production of powerful yet inexpensive laser light sources.

    摘要: The present invention relates to the packaging of high power laser(s) in a surface mount technology (SMT) configuration at low-cost using wafer-scale processing. A reflective sidewall is used to redirect the output emission from edge-emitting lasers through an optical element (e.g., a diffuser, lens, etc.). A common electrical pad centered inside the package provides p-side connection to multiple laser diodes (i.e. for power scalability). Thick plating (e.g. 75 um to 125 um) with a heat and electrically conductive material, e.g. copper, on a raised bonding area of a substrate provides good heat dissipation and spreading to the substrate layer during operation. The composite CTE of the substrate layer, e.g. AlN, and the heat/electrical conductive plating, e.g. Cu, substantially matches well with the laser substrates, e.g. GaAs-based, without the requirement for an additional submount.

    摘要: A programmable laser driver may be programmed to meet the characteristics of a particular laser. Traditionally, external resistors are used to bias the driver and program the value of the drive current to suit a particular laser. Embodiments of the present invention comprise integrating a plurality of resistors with the IC driver and providing a bonding bad for each resistor. Thus, different drive currents may be selectable based on different bonding patterns corresponding to different bias resistance selections. These bond options allow the selection of different ranges of bias current, modulation current and temperature coefficients necessary to drive various lasers.
