Abstract

Optical detectors based on YBa₂Cu₃O_7-δ thin films have been fabricated, which show a response time of a few ns. Typical dimensions of the active area are 10×10 μm². No preamplifier is needed during operation. The authors report on the optical response of detectors having nongranular and fine-grain morphologies to different sources of pulsed laser radiation (e.g., mode-locked Nd:YLF laser at 1.3 μm and a GaAs diode laser at 0.9 μm). Emphasis in the study is placed on detection sensitivity for measuring short optical pulses. It is found that the best noise obtained with a fine-grain detector is on the order of 10^-10 W/Hz^1/2, when irradiated by the 65ns-pulse-width diode laser.
