Abstract: A light emitting device, a transmitter, and a silicon photonics chip, among other things, are disclosed. An illustrative light emitting device is disclosed to include a silicon substrate, a waveguide disposed on or integrated in the silicon substrate, where the waveguide includes a wide waveguide section at a first end and a narrow waveguide section at a second end, a first metal pad disposed over the wide waveguide section and at least partially across the first end of the waveguide, and a second metal pad disposed over the wide waveguide section, distanced away from the first metal pad. Electrical current passing between the first metal pad and the second metal pad may cause light to be produced in the wide waveguide section and the light produced in the wide waveguide section is at least partially reflected by the first metal pad and directed to the narrow waveguide section for transmission.

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: 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: 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.

Abstract: Network devices and associated methods are provided for synchronization in an optically switched network. The network device includes one or more ports in communication with a plurality of devices via an optical switch. The one or more ports receive a master clock signal having a first frequency from a first device of the plurality of devices. The network device includes a local clock in communication with the one or more ports and operating at a second frequency. The network device includes a synchronization manager in communication with the one or more ports and the local clock and configured to be enabled and disabled. When the synchronization manager is enabled, it receives the master clock signal via the one or more ports and transmits an instruction to the local clock to operate at the first frequency.

Abstract: The disclosure addresses the problem of increased optical insertion losses in integrated optical switches. It enables the implementation of an array of optical amplifiers, typically with low/moderate gain, to compensate for optical insertion losses in the integrated switches. The amplifier is based on a doped optical fiber which is optically pumped by a pump laser. The integrated optical switch includes a transposer that facilitates connectivity between a set of fibers and a photonic chip through an optical mode conversion. An all passive circuitry is built in a doped fiber amplifier, WDM couplers combine/separate the signals from the pump, and splitters allow sharing of a single pump by multiple amplifiers. In addition, switch pigtails are implemented with the doped fiber.

Abstract: Embodiments are disclosed for generating an optical Pulse Amplitude Modulation 4-level (PAM-4) signal from bandwidth-limited duobinary electrical signals in a Mach-Zehnder modulator. An example system includes an MZM structure that comprises a first waveguide interferometer arm structure associated with a first semiconductor device and a second waveguide interferometer arm structure associated with a second semiconductor device. A polybinary electrical signal is applied to or between the first semiconductor device and the second semiconductor device to convert an input optical signal provided to the MZM structure into an optical PAM-4 signal.
