    摘要: A vertical-cavity surface-emitting laser incorporating a supported air gap distributed Bragg reflector is disclosed. The supported air gap DBR includes a regrowth layer of material that provides mechanical support for the original material layers. The supported air gap DBR is fabricated by first growing alternating pairs of a first material and a sacrificial material over a suitable substrate. The layer pairs of the first material and sacrificial material are covered by a suitable dielectric material. The dielectric material is then selectively removed exposing regions of the first material and sacrificial material where selective regrowth of additional material is desired. The selective regrowth of the additional material provides mechanical support for the semiconductor material that remains after a selective etch removal of the sacrificial material.

    摘要: A distributed Bragg reflector and a method of fabricating the same incorporates a support for supporting the gaps against collapse. The method includes forming a plurality of alternating structure and sacrificial layers on a substrate. The structure and sacrificial layers are etched into at least one mesa protruding from the substrate. A support layer is formed on the at least one mesa leaving a portion of the structure and sacrificial layers exposed. At least a portion of at least one of the exposed sacrificial layers are etched from between the structure layers to form gaps between the structure layers.

    摘要: In one embodiment, there is disclosed a waveguide medium using total internal reflection to create a relatively sharp (approximately 90°) bend for optical signals traversing the waveguide. A discontinuity of the medium (such as air) is used to create a turning mirror within the waveguide path. By curving the discontinuity, the entire input optical signal is focused into the output portion of the waveguide, thereby compensating for the diffraction loss of the optical signal at the bend. In one embodiment in order to facilitate proper alignment of the masks certain portions of the waveguide on a first mask are extended (widened) beyond their optimum physical size. This extended portion is then used to position an edge of a second mask, such that optical signal scatter caused by the extended portions of the waveguide are compensated for by adjusting the curvature.

    摘要: A computing system includes an optical transmission media to propagate a single-mode signal and a multimode signal, and support mode matching with the single-mode signal and multimode signal. A lowest-order mode of the optical transmission media is to couple the single-mode signal, and at least one higher-order mode of the optical transmission media is to couple the multimode signal. The optical transmission media is to enable extraction of the single-mode signal from the optical transmission media independently of the multimode signal.

    摘要: Various embodiments of the present invention are directed to optical-based methods and expansion memory systems for disaggregating memory of computer systems. In one aspect, an expansion memory system comprises a first optical/electronic interface in electrical communication with a processor, a memory expansion board configured with memory, and a second optical/electronic interface attached to the memory expansion board. The first interface converts optical signals into electronic signals that are sent to the processor and converts electronic signals produced by the processor into optical signals. The second interface converts optical signals into electronic signals that are sent to the memory and converts electronic signals produced by the memory into optical signals. The optical signals are exchanged between the first and second interfaces. Embodiments also include methods for sending and receiving data in an expansion memory system.
