Abstract

After discussing the sensitivity limit of optical PSK homodyne receivers we describe the realisation and properties of a mechanically cooled photodiode/preamplifier module used in our breadboard model of a 10 _pm receiver. Several receiver concepts are described which have in common frequency and phase synchronization between input signal and local laser oscillator signal with a phase-locked loop (PLL) control circuit. Means to avoid DC-coupling of the PLL are discussed. The results of bit error measurements with an ordinary, DC-coupled homodyne receiver operated at 140 Mbit/s are presented.
