  • Patent number: 10605148
    Abstract: An article of manufacture includes a rigid plate, first and second tab members defined by a pair of substantially diametrically-opposed U-shaped apertures within the plate, and a third tab member defined by a U-shaped aperture proximal to the first and the second tab members. The article of manufacture can be used as an active exhaust defeat device, providing the capability of locking a butterfly valve of a vehicle active exhaust system in a desired orientation. Although the butterfly valve is locked, which may be a non-standard exhaust configuration, the article of manufacture provides that vehicle error codes specific to an exhaust valve actuator are avoided.

  • Patent number: 8687664
    Abstract: A laser assembly comprises a substrate, one or more standoffs and a semiconductor laser. The substrate has a first doped region and a second doped region. The second doped region is proximate to an upper surface of the substrate and forms a pn junction with the first doped region. The semiconductor laser is operative to emit light from an upper surface and a lower surface. Moreover, the semiconductor laser is attached to the upper surface of the substrate with the one or more standoffs such that the light emitted from the lower surface of the semiconductor laser impinges on the second doped region.

  • Patent number: 8165180
    Abstract: 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.

  • Patent number: 7772085
    Abstract: 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.
