Large Area Ge Schottky Barrier Photodetector for Attentuation Measurements of Optical Fibers at Long Wavelengths

摘要

The construction of a cooled (77 K) large area Schottky barrier Ge photodetector, based on high purity intrinsic raw material, and its application for the attenuation measurements of the optical fibers at long wavelengths up to about 1700 nm, is presented.
