Abstract

We demonstrate a 40 Gb/s DPSK secure optical communication system using 40Gchip/s time stretched optical spectral phase encoding and symbol overlapping. Security robustness against eavesdropping attacks have been demonstrated for ultra-long optical codes with 128-, 512- and 1024-chip in the experiment.
