Abstract

The negentropy principle of information will be reviewed and applied to communication using photons. In this context, Landauer's interpretation of the Szilard engine, which converts information into a decrease in entropy, will be discussed. The amount of information transmitted by photons will be determined for various limiting cases. Finally, a practical high bit-rate optical fiber communication system performance will be presented and compared with the ideal limits.
