Terminals for a high-speed optical pulse code modulation communication system: II. Optical multiplexing and demultiplexing

Techniques are described for optically multiplexing and demultiplexing individual pulse code modulation (PCM) channels in order to develop the terminal capability for a high-capacity optical communication system. It is shown that, using these techniques, an information capacity in excess of 10
¹⁰
bit/s can be achieved on the output beam of a single laser.
