摘要： A cryogenic optoelectronic data link, comprising a sending module operating at a cryogenic temperature less than 100 K. An ultrasensitive electro-optic modulator, sensitive to input voltages of less than 10 mV, may include at least one optically active layer of graphene, which may be part of a microscale resonator, which in turn may be integrated with an optical waveguide or an optical fiber. The optoelectronic data link enables optical output of weak electrical signals from superconducting or other cryogenic electronic devices in either digital or analog form. The modulator may be integrated on the same chip as the cryogenic electrical devices. A plurality of cryogenic electrical devices may generate a plurality of electrical signals, each coupled to its own modulator. The plurality of modulators may be resonant at different frequencies, and coupled to a common optical output line to transmit a combined wavelength-division-multiplexed (WDM) optical signal.

摘要： Methods, systems, and devices are described for electro-optic tuning. An example device may comprise a first layer comprising a transition metal di-chalcogenide material, a second layer comprising a conductive material, and a third layer comprising a dielectric material. The third layer may be disposed at least partially between the first layer and the second layer. An electrical potential difference applied between the first layer and the second layer may cause a tunable refractive index change in the first layer.

摘要： An optical apparatus for coupling an optical fiber to a waveguide is disclosed. The optical apparatus can comprise a funnel coupler having an orifice configured to receive an optical fiber. The funnel coupler can mechanically support the optical fiber when received in the orifice. The funnel coupler can guide the optical fiber to a coupling end of the funnel coupler and a waveguide disposed adjacent the coupling end of the funnel coupler. One or more of the funnel coupler or the waveguide can be configured to optically couple the optical fiber and the waveguide when the optical fiber is received in the orifice.
