Abstract: III-V lasers integrated with silicon photonic circuits and methods for making the same include a three-layer semiconductor stack formed from III-V semiconductors on a substrate, where a middle layer has a lower bandgap than a top layer and a bottom layer; a mirror region monolithically formed at a first end of the stack, configured to reflect emitted light in the direction of the stack; and a waveguide region monolithically formed at a second end of the stack, configured to transmit emitted light.

Abstract: A grating structure has a plurality of gratings. In one example, one or more of the gratings are configured: to be non-uniformly spaced with respect to one or more other ones of the gratings; and to optically couple a first light conduit and a second light conduit enabling light having a first polarization and light having a second polarization to pass through the grating structure and propagate in the same direction in the first light conduit or the second light conduit. The non-uniform spacing of the gratings may represent an intersection or a union of a period associated with the light having the first polarization and a period associated with the light having the second polarization.

Abstract: A method for cloaking an object from an observer is provided in the illustrative embodiments. A hardware device is affixed to the object such that the observer observes a presentation on the device when observing the object. The device is enabled to receive a signal, wherein the signal corresponds to a portion of an ambience obscured by the object from a view of the observer. The signal is processed, at the device and without using a data processing system, to generate a version of the signal. Using the device, the version of the signal is presented to the observer as the presentation, wherein the version of the signal cloaks the object from the ambience in the view of the observer.

Abstract: A contact structure and assembly for a microelectronics device includes first and second electrically conductive contacts being helically shaped. A carrier element is attached to and positioned between the first and second contacts. The first and second contacts are in electrical communication with each other, and the first and second contacts are in a mirror image relationship with each other. A pair of insulating substrates each include electrically conductive members. A contact point on each of the first and second contacts is attached and electrically communicating to respective electrically conductive members such that the first and second electrically conductive contacts between the pair of insulating substrates form an electrically conductive package. A metal layer on the carrier element provides electrical conductivity through a first opening defined by the carrier element between the first and second portions of the helix shaped contact.
