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.
