Abstract

We have demonstrated an optical detector based on patterned YBa2Cu3O7-δ thin films. The responses up to 18 GHz were observed using two wavelength lasers. The amplitude of the light was modulated up to 18 GHz by an optical heterodyne mixing system. The responsivity of the detectors is over 50 V/W for different wavelength lasers below 1 Hz and the responsivity is 4 mV/W at the 780 nm wavelength and 30 mV/W at 1.5 μm in the region from 3 GHz to 18 GHz. Our detector is one of the promising candidates for highly sensitive and wideband optical receiver.
