  • Patent number: 11988871
    Abstract: A technology is described for a Photonic Integrated Circuit (PIC) radio frequency (RF) oscillator. The PIC RF oscillator can comprise an optical gain media coupled to a first mirror and configured to be coupled to the PIC. The PIC can comprise a first optical cavity located within the PIC, a tunable mirror to form a first optical path between the first mirror in the gain media and the first tunable mirror, and a frequency tunable intra-cavity dual tone resonator positioned within the first optical cavity to constrain the first optical cavity having a common optical path to produce tow primary laser tones with a tunable frequency spacing. A photo detector is optically coupled to the PIC and configured to mix the two primary laser tones to form an RF output signal with a frequency selected by the tunable frequency spacing of the two primary tones.

  • Patent number: 11971997
    Abstract: Techniques for automated system requirements analysis are disclosed. A system requirements analysis (SRA) service generates a system model that includes system requirements, at least by performing natural-language processing on a natural-language representation of the system requirements. Based at least on the system model, the SRA service performs an analysis of the system requirements against codified system requirements rules. The SRA service determines, based at least on the analysis of the system requirements against the codified system requirements rules, that the system requirements include a violation of a system requirements rule. The SRA service generates a report that identifies at least (a) the violation of the system requirements rule and (b) a suggested action to remediate the violation of the system requirements rule.

  • Patent number: 11909442
    Abstract: A technology is described for a Photonic Integrated Circuit (PIC) radio frequency (RF) in-phase quadrature phase (I/O) correlator. The PIC RF Correlator can comprise two optical waveguides to receive first and second optical signals that are modulated by first and second RF signals, respectively. Two 1 to M optical splitters can split the first and second RF modulated optical signals. Optical delay lines can delay the M split first RF modulated optical signals. M optical balanced couplers can receive and combine the M first delayed RF modulated optical signals with the M split second RF modulated optical signals. Balanced photodetectors can output a differential integration on the first and second combined RF modulated optical signals for in-phase and quadrature phase signals. A processor can add the outputs of the M optical balanced photodetectors to form a frequency domain correlated signal of the first and second RF signals with real and imaginary parts.

  • Patent number: 11889311
    Abstract: Embodiments of a radio-frequency (RF) repeater configured for semantic-less retransmissions are described herein. The RF repeater performs physical (PHY) layer processing to identify one or more PHY layer features of a received RF signal. The RF repeater may determine whether or not to retransmit the received RF signal based on the one or more PHY features. The determination to retransmit the received RF signal may be based solely on PHY parameters enabling semantic-less retransmissions.

  • Patent number: 11860034
    Abstract: A technology is described for hyperspectral imaging. An example of the technology can include receiving an event stream of events from an event camera coupled to an interferometer. The event camera can receive light output from the interferometer and generate the event stream, comprising event data that corresponds to the light output. The events in the event stream can indicate a pixel that detected an event, a time of the event, and a polarity of change in brightness detected by the pixel. Spectral data can be generated for the events in the event stream using a demodulation and frequency transform to convert temporospatial aggregates of events in the event stream to frequency domain data that corresponds to an optical spectrum. A hyperspectral image of an input scene in a spectral range can be generated using the spectral data.
