Abstract

A cooler/detector/preamplifier unit to be used as the front end in coherent optical receivers for X = 10pm was designed, fabricated, and tested. Both the HgCdTe-detector and the preamplifier were cooled to 80 K with the aid of a Stirling cooler. The three-stage high-impedance preamplifier realized employs field effect transistors and can hence be operated at low temperatures, too. Receiver tests were performed at a data rate of 140 Mbit/s using a quasi-homodyne receiver setup, with the bit-error-rate as the criterion of performance. Receiver operation very close to the quantum limit was demonstrated.
