  • Patent number: 10686293
    Abstract: A system for self-aligning assembly and packaging of semiconductor lasers allows reduction of time, cost and testing expenses for high power density systems. A laser package mounting system, such as a modified TO-can (transistor outline can), has modifications that increase heat transfer from the active laser to a heat exchanger or other heat sink. A prefabricated heat exchanger assembly mounts both a laser package and one or more lenses. Direct mounting of a fan assembly to the package further minimizes assembly steps. Components may be physically and optically aligned during assembly by clocking and other indexing means, so that the entire system is self-aligned and focused by the assembly process without requiting post-assembly adjustment. This system can lower costs and thereby enable the use of high powered semiconductor lasers in low cost, high volume production, such as consumer items.

  • Patent number: 10137543
    Abstract: A compound optical assembly is constructed from a plurality of stacking elements for spacing, aligning, and retaining optical elements within the assembly. Stacking faces of the stacking elements are measured and low-order surface errors are extracted, represented by mathematical approximations having a primary angular frequency. The stacking elements including the optic holders are relatively oriented to promote complementarity between the low-order surface errors of mating stacking faces.

  • Patent number: 9929531
    Abstract: An optical module includes a base portion having a top-surface metal layer on a top surface of a base, a semiconductor element on the top-surface metal layer and an optical element optically-coupled to the semiconductor element and bonded to the base with adhesive at a first side surface of the base at a side of the optical element being optically-coupled. A pull-back area is formed on the top surface by disposing a second side surface at the side, of the top-surface metal layer at a retracted position to the first side surface at the side. Between an adhesion area where the base and the optical element are bonded and a mounting portion below an optical-power-outputting surface of the semiconductor element, the top-surface metal layer has an adhesive flow stopping portion formed, by patterning, so as to prevent the adhesive from flowing through the pull-back area to the mounting portion's side.
