摘要： A holding apparatus including a fixture is described. The fixture of the holding apparatus, which receives a semiconductor laser bar for optical coating, includes a base and a pair of walls. The walls and the base have inner surfaces, and the walls have a top surface upon which the laser bar rests. An extending portion of the semiconductor laser bar fits in a cavity formed by the base and the walls. The facet edges of the laser bar do not extend horizontally beyond the walls of the fixture. A coating apparatus applies a coating to the facet edges of the laser bar without contacting any coating material on the extending portion.

摘要： An optical disk playback device comprises one or more lasers, an optical assembly, an optical detector, and controller circuitry coupled to the optical detector. The optical assembly is configured to direct incident light from the one or more lasers so as to form first and second scanning spots on a surface of an optical disk, and is further configured to direct corresponding reflected light from the first and second scanning spots on the surface of the optical disk to the optical detector. The optical detector is configured to process the reflected light from the first and second scanning spots to generate respective first and second data streams, and the controller circuitry is configured to generate a three-dimensional image signal from the first and second data streams.

An area under a hypothetical wire bond profile is calculated as a function of the bond distances, a baseline wire length, and a baseline loop height. A wire is bonded across a given one of the bond distances to form a given one of the wire bonds. A wire bond profile for the given wire bond is provided having an area thereunder that is substantially equal to the calculated area.

摘要： Embodiments of the invention include a laser structure having a delta doped active region for improved carrier confinement. The laser structure includes an n-type cladding layer, an n-type waveguide layer formed adjacent the n-type cladding layer, an active region formed adjacent the n-type waveguide layer, a p-type waveguide layer formed adjacent the active region, and a p-type cladding layer formed adjacent the p-type waveguide layer. The laser structure is configured so that a p-type dopant concentration increases across the active region from the n-type side of the active region to the p-type side of the active region and/or an n-type dopant concentration decreases across the active region from the n-type side of the active region to the p-type side of the active region. The delta doped active region provides improved carrier confinement, while eliminating the need for blocking layers, thereby reducing stress on the active region caused thereby.

摘要： A manufacturing method, in which two device bars are bonded prior to facet coating to form a stacked bar pair. In one embodiment, each of the device bars has a p-side and an n-side, each side having a plurality of bonding pads, with at least some bonding pads located at the p-side of the first device bar adapted for mating with the corresponding bonding pads located at the p-side of the second device bar. Solder material deposited onto the p-side bonding pads adapted for mating is liquefied in a reflow oven, wherein surface tension of the liquefied solder self-aligns the device bars with respect to each other and keeps them in alignment until the solder is solidified to form a solder bond between the mated bonding pads. Two or more instances of the bonded bar pair are further stacked such that bonding pads located at the n-sides of adjacent bar pairs are mated in a relatively tight fit. The exposed facets in the resulting stack are then spray-coated with one or more reflective materials, with the solder bonds between the p-side bonding pads and the tight fit between the n-side bonding pads protecting those pads from overspray coating.
