Summary

The aim of this project is to experimentally demonstrate that chaotic external cavity semiconductor lasers can be used to provide a high data rate secure communication channel. The project will study the security of a GHz data transmission system that uses the chaotic output of a laser diode to mask the data signal. The project will provide proof-of-principle experimental results, and will quantify the degree of security this encryption format can provide. This work will be accomplished by using commercially available laser diodes supplied by NORTEL Networks.
