Paper Abstract

The optical response of granular films of YBa2Cu3O7-x to pulsed far infrared radiation has been measured. The infrared light energies ranged from 2.5 to 19 meV. Direct coupling to intergrain Joseph-son currents dominates the 3.2 meV photoresponse. Such direct coupling effects are considerably reduced for 10.9 and 19.1 meV light. These results will be interpreted in terms of possible magnitudes for the superconducting energy gap in YBCO.
