Abstract
A novel optical homodyne receiver for binary PSK optical communication systems that can break the receiver sensitivity limit determined from the shot noise is proposed. The receiver consists of the optical preamplifier, the feedforward circuit to reduce the signal-spontaneous beat noise, and the conventional double-balanced homodyne receiver. The operation principle of the receiver and the analysis of the sensitivity are described.<>
