Abstract: A microwave resonator device including a first resonator member comprised of a dielectric material and a second resonator member comprised of a dielectric material. The second resonator member can be positioned spatially offset from the first resonator member to define a spatial interaction region configured to confine an electromagnetic field in a microwave region of the electromagnetic spectrum. The spatial offset between the first resonator member and the second resonator member defining the spatial interaction region is less than the microwave wavelength associated with a resonant frequency of the microwave resonator device. The microwave resonator device facilitates generation of a resonant field enhancement within the spatial interaction region.

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.

Abstract: A photonic processor computing engine device can include a photonic integrated circuit including an optical phased array having a plurality of radiating pixels that radiate optical signal beams. Each of the radiating pixels can include an optical antenna and an optical phase modulator. The engine can include an electronic control circuit positioned to receive the optical signal beams transmitted from the radiating pixels. The computing engine can further include an electronic feedback circuit in electrical communication with the focal plane array and the electronic control circuit to process a measured intensity of the optical signal beams received by the focal plane array from the optical phased array and provide a feedback signal to the electronic control circuit based on the measured intensity for recalibrating the optical phase modulators of the plurality of radiating pixels to control the phase of the optical signal beams emitted by the plurality of radiating pixels.

Abstract: A photonic integrated circuit (PIC) is disclosed herein. The PIC can include a substrate, a main optical waveguide supported by the substrate. The main optical waveguide can be in communication with an electromagnetic radiation source, and configured to receive electromagnetic radiation from the electromagnetic radiation source. A first branch optical waveguide can be optically coupled to the main optical waveguide at a first location. An optical phased array (OPA) can include plurality of array elements, each having an optical antenna and an optical phase modulator. At least some array elements within a first subset of the plurality of array elements can be optically coupled to the first branch optical waveguide wherein locations of at least some of the plurality of array elements are aperiodic in one or more directions on the substrate.

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.
