Abrégé

Embodiments of the present invention relate to a superconducting signal storage circuit for integrating and/or storing signals locally as current that can be stored indefinitely in a superconducting wire or inductor. Low-noise readout is accomplished through a transistor circuit that transduces the integrated current signal to a charge on a capacitor. A nanocryotron element generates a voltage across its channel when a sum of the integrated current and a ramp current applied by the transistor circuit reaches a threshold value. This generated voltage switches the gates of an inverter, which terminates the current flow to the capacitor. The accumulated charge on the capacitor is proportional to the current in the storage element that was present when the nanocryotron sensing gate switched from the superconducting state to the resistive state. The charge on capacitor is read by opening a transistor to provide an access line to the capacitor.

An apparatus for light delivery to magneto-optical trap (MOT) system utilizes only planar optical diffraction devices including a planar-integrated-circuit PIC and a metasurface MS. When MOT is based on the use of a diffraction grating, a grating chip is additionally employed to launch and manipulate light for laser cooling. Bridging the gap between the sub-micrometer-scale guided mode on the PIC and the centimeter-scale beam needed for laser cooling, a magnification of the mode area by about 1010 is demonstrated using an on-chip extreme-mode-converter to launch a Gaussian mode into free space from a PIC-waveguide and a beam-shaping, polarization-dependent MS to form a diverging laser beam with a flat-top spatial profile, which efficiently illuminates the grating chip without loss of light. Comparison to equivalent Gaussian-beam-illuminated GMOTs evidences advantageous power efficiency of operation of the proposed light delivery system as compared with conventional systems employing Gaussian distribution of illumination at the grating chip.

A millimeter-wave frequency synthesizer generates a millimeter wave by photomixing two Kerr-soliton microcombs. A single-frequency laser beam is modulated to create first and second pump components having first and second pump frequencies. The first pump component excites a first microresonator to create a first microcomb while the second pump component excites a second microresonator to generate a second microcomb. A pair of comb lines from the two microcombs is detected to generate a low-frequency beat note that is phase-locked by identically tuning the pump frequencies. Another pair of comb lines is detected with a high-speed photodiode to generate the millimeter wave. The frequency of the millimeter wave is based on (i) the difference between the pump frequencies, (ii) the difference between the repetition rates, and (iii) the index of the comb lines that are photomixed to generate the millimeter wave.
