  • Optical superconducting device
    Patent number: 6815708
    Abstract: An optic superconducting circuit element (10) is disclosed that is operable to transmit and receive on an identical chip an electromagnetic wave having frequencies in an extended frequency band ranging from microwave to THz frequency bands and with high sensitivity. The optic superconducting circuit element (10) includes the chip (3), and a superconducting electromagnetic wave oscillating (generating and transmitting) source (16) and a superconducting Josephson junction device (14) disposed in close vicinity to each other on the chip (3), the superconducting Josephson junction device (14) detecting the electromagnetic wave transmitted from the superconducting electromagnetic wave oscillating (generating and transmitting) source (16).
