An optical heterodyne mixing technique was developed to study the photoresponse in patterned YBa2Cu3O7−δ (YBCO) thin film. Our mixing system is composed of two identical 1.54 μm wavelength laser diodes and the laser light is introduced without op

High quality superconducting YBa2Cu3O7-δ (YBCO) thin films were fabricated with ex situ co-evaporation on SrTiO3 and in situ laser deposition on (001) MgO substrates. The co-evaporated films gave a superconducting transition temperature, Tc ~ 90 K,

We have measured the optical responses up to 18 GHz in patterned YBa2Cu3O7−δ thin films at various wavelengths by optical heterodyne mixing. The responsivity of the detectors is higher than 50 V/W below 1 Hz at various wavelengths and the responsi
