Fast Resonance Frequency Optical Modulation in Superconducting Stripline Resonator

Fast resonance frequency optical modulation of a superconducting stripline resonator is investigated. The experiments are performed using a novel device which integrates a hot electron detector (HED) into a superconducting stripline ring resonator. Frequency modulation is demonstrated by both applying dc current or voltage to the HED, and by applying optical illumination, with modulation frequencies of up to 4.2 GHz. Potential applications for such a device are in telecommunication, quantum cryptography, and biofluorescence
