Abstract: A high performance mechanism for exporting peripheral services and offloads using Direct Memory Access (DMA) engine is presented. The DMA engine comprises a ring buffer, a DMA memory, and a DMA engine interface operatively coupled to the ring buffer and the DMA memory. The DMA engine interface is configured to retrieve, from the ring buffer, a first DMA request; extract first transfer instructions from the first DMA request; retrieve a first data corresponding to the first DMA request from the DMA memory; and execute the first DMA request using the first data based on at least the first transfer instructions.

Abstract: High-bandwidth lasers having a balanced intrinsic response and parasitic response are described herein. For example, the present invention may be directed to a laser having an optimized parasitic transfer function and for which the bandwidth of the intrinsic response of the laser is increased by increasing a differential gain of the laser. The laser may balance increased bandwidth of the intrinsic transfer function due to increased cavity length with reduced bandwidth of the parasitic transfer function due to increased active resistance. For example, embodiments of the present invention may be directed to a laser configured to operate at an operating wavelength selected to maximize the bandwidth of the total response of the laser.

Abstract: Some embodiments of the present invention are directed to a mode-filtered VCSEL having a multi-layer oxide aperture for high-bandwidth and side-mode suppression. The oxide aperture may include multiple layers having different aluminum fractions configured to increase an SMSR of the VCSEL while maintaining longitudinal confinement. The oxide aperture may be formed from a mirror layer of the VCSEL proximate an active region. The mirror layer may include first epitaxial layers closest to the active region having a first aluminum fraction selected to longitudinally confine the optical field of the VCSEL. The mirror layer may include second epitaxial layers having a second aluminum fraction low enough to prevent substantial oxidation of the second epitaxial layers. Additionally, the mirror layer may include third epitaxial layers having a third aluminum fraction greater than the first and second aluminum fractions. The third epitaxial layers may be oxidized to form the oxide aperture.

Abstract: Embodiments are disclosed for a quantum key distribution enabled intra-datacenter network. An example system includes a first vertical cavity surface emitting laser (VCSEL), a second VCSEL and a network interface controller. The first VCSEL is configured to emit a first optical signal associated with data. The second VCSEL is configured to emit a second optical signal associated with quantum key distribution (QKD). Furthermore, the network interface controller is configured to manage transmission of the first optical signal associated with the first VCSEL and the second optical signal associated with the second VCSEL via an optical communication channel coupled to a network interface module.

Abstract: Processes for laminating a conductive-lubricant coated Printed Circuit Board (PCB) are disclosed. An example laminated PCB may include a lamination stack that may further include a core, an adhesive layer, and at least one graphene-metal structure or at least one hexagonal Boron Nitride metal (h-BN-metal) structure. The materials of the PCB may change in accordance with the invention described herein, including the materials of the core, the materials of the conductive-lubricant coatings, or the metal layers of the conductive-lubricant-metal structures. Doping processes for each change in materials used are also described herein. The conductive-lubricant of the conductive-lubricant-metal structure will promote high frequency performance and heat management within the PCB. Furthermore, a removal process of those materials post-lamination is described herein to promote protection of materials and subsequent removal of protective layers without breakage or tearing.

Abstract: Various embodiments of the present disclosure are directed to accessing a quantum communication channel undetected and/or characterizing this communication channel based upon attempted access. An example method includes accessing a quantum communication channel transmitting one or more qubits. The method includes the introduction of a noise signal to the quantum communication channel and then applying in its absence one or more weak or variable-strength measurements to the quantum communication channel. A strength of at least one measurement of the one or more measurements is based at least in part upon the current noise signal. The method further includes obtaining information associated with the one or more qubits based on the one or more measurements.

Abstract: Bi-directional quantum interconnects are provided that include a first communication module and a second communication module. The first communication module includes a first quantum transmitter and a first quantum receiver, and the second communication module includes a second quantum transmitter and a second quantum receiver. The example interconnect further includes a first communication medium communicably coupling the first communication module and the second communication module such that communication is provided between the first quantum transmitter and the second quantum receiver and between the second quantum transmitter and the first quantum receiver via the first communication medium. The first quantum transmitter and the second quantum transmitter generate qubits having first and second quantum characteristics, respectively, to allow for bi-directional quantum communication over a common channel.

Abstract: Systems, computer program products, and methods are described herein for network discovery, port identification, and/or identifying fiber link failures in an optical network, in accordance with an embodiment of the invention. The present invention may be configured to sequentially connect each port of an optical switch to a network port of a server and generate, based on information associated with network devices connected to the ports, a network map. The network map may identify which network devices are connected to which ports of the optical switch and may permit dynamic port mapping for network installation, upgrades, repairs, and/or the like. The present invention may also be configured to determine a fiber link in which a failure occurred and reconfigure the optical switch to allow communication between an optical time-domain reflectometer and the fiber link to test the fiber link.
