Abstract
The present invention relates to a receiver for receiving a time division multiplexed (TDM) optical signal, which is formed of a plurality of interleaved optical pulse streams. Each optical pulse stream includes a plurality of optical pulses. The receiver includes a detector for detecting at least a first optical pulse stream of the optical signal and an optical hybrid for coherently mixing the first optical pulse stream with a reference pulse stream. The first optical pulse stream and the reference pulse stream impinge simultaneously upon the detector.
