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： Embodiments of the present disclosure provide devices and methods involving the thermal stabilization of microring resonators, such as microring modulators. Power is measured via an on-chip photodetector integrated with a drop port of the microring resonator, providing a local measurement of average power. This average power is employed as a feedback measure to actively control a heater that is integrated with the microring resonator, in order to stabilize the resonant wavelength of the microring resonator in the presence of thermal fluctuations. Employing such a system, a microring modulator can maintain error-free performance under thermal fluctuations that would normally render it inoperable.
