摘要： 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.

摘要： 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.

摘要： A network device includes at least one port, a memory, data-path circuitry, and a processor. The at least one port is to exchange packets with a network. The data-path circuitry is to process the packets. The memory is to store signatures of traffic patterns according to a locality-sensitive signature function., and corresponding parameter settings for the data-path circuitry. The processor is to assess a current traffic pattern of the packets, to calculate a current signature over the current traffic pattern using the locality-sensitive signature function, to query the memory using the current signature, to configure the data-path circuitry, in response to finding a stored signature that is within a specified distance from the current signature, with a parameter setting that corresponds to the found signature, and take an alternative action in response to finding that no stored signature is within the specified distance from the current signature.

摘要： A network adapter includes a network interface, a host interface and processing circuitry. The network interface is configured to connect to a communication network. The host interface is configured to communicate with a host processor running multiple application programs. The processing circuitry includes one or more bandwidth-control policers, and is configured to receive from the communication network a packet destined to a given application program among the application programs running on the host processor, to associate a bandwidth-control policer with the packet, selected from among the bandwidth-control policers, and to apply the selected bandwidth-control policer to the packet to produce a policer result.
