摘要： A mesh network node can include a self-interference cancellation subsystem. Operation of the self-interference cancellation subsystem enables persistent and/or continuous spectrum monitoring by the mesh network node. The mesh network node can transmit spectrum information at one or more intervals to a spectrum access server which can leverage spectrum information provided by multiple mesh nodes to optimize connections and/or links between nodes in the mesh network.

摘要： An optical filter comprises an array of waveguides fabricated on an optical integrated circuit (PIC). The array comprises individual waveguides, each of which receive light inputs, e.g., individual taps of a multi-tap optical filter used in an interference cancellation circuit. Typically, the output(s) of the individual waveguides are located at an exit (edge) of the PIC. At least one second waveguide in the array is patterned on the PIC in a converged configuration such that the light transiting these waveguides co-propagates and interacts across given portions of the respective waveguides before exiting the waveguide array along a common facet, thereby generating or inhibiting one of intermodulation products, and harmonics. This structural configuration enables the generation of various modes of transmission at the PIC exit, enabling more efficient transfer of the energy, e.g., to an associated photodetector (PD) that provides conversion of the energy to the RF domain.

摘要： A wireless communication device can include a transmitter subsystem configured to transmit a transmit signal that, once propagated from the wireless communication device, may be reflected back and received by a receiver subsystem as interference. The wireless communication device can include a self-interference cancellation subsystem configured to generate a cancellation signal to mix with received signals to mitigate self-interference effects. A performance floor for the self-interference cancellation subsystem may be determined based on a phase noise profile of an oscillator of either or both the transmitter subsystem or the receiver subsystem. The performance floor metric can be thereafter used to inform an operation or operational setting of the wireless communication device.

摘要： A dicing system and methods may include a novel way to separate die on a wafer in preparation for packaging that results in smooth diced edges. This is specifically advantageous, but not limited to, edge-coupled photonic chips. This method etches from the front side of the wafer and dices from the back side of the wafer to create a complete separation of die. It creates an optically smooth surface on the front side of the wafer at the location of the optical device (waveguides or other) which enables direct mounting of adjacent devices with low coupling loss and low optical scattering. The backside dicing may be wider than the front side etch, so as to recess this sawed surface and prevent it from protruding outward, resulting in rough surfaces inhibiting a direct joining of adjacent devices.

摘要： A signal generator includes a photonic circuit configured to output a sequence of solitons at a known rate. The solitons illuminate a high-speed photodiode that, in response, generates an electrical signal, such as a sinusoidal signal, which can be provided as input to a direct digital synthesizer configured to output successive phases of a selected waveform in response to electrical stimulus.

摘要： Methods and apparatus for interference cancelation in a radio frequency communications device are described. In various embodiments a signal to be transmitted in converted into an optical signal and processed using an optical filter assembly including one or more optical filters to generate an optical interference cancelation signal. The optical interference cancelation signal is converted into an analog radio frequency interference cancelation signal using an optical to electrical converter prior to the analog radio frequency interference cancelation signal being combined with a received signal to cancel interference, e.g., self interference. The optical filter assembly can include a large number of taps, e.g., 30, 50, 100 or more. Each tap may be implemented as a separate optical filter or series of optical filters. Delays and/or gain of the optical filters can be controlled dynamically based on channel estimates which may change due to changes in the environment and/or communications device position.
