Optical code division multiple access secure communications systems with rapid reconfigurable polarization shift key user code

Abstract

Abstract. An optical code division multiple access (OCDMA) secure communications system scheme with rapid reconfigurable polarization shift key (Pol-SK) bipolar user code is proposed and demonstrated. Compared to fix code OCDMA, by constantly changing the user code, the performance of anti-eavesdropping is greatly improved. The Pol-SK OCDMA experiment with a 10 Gchip∕s user code and a 1.25 Gb∕s user data of payload has been realized, which means this scheme has better tolerance and could be easily realized. © The Authors.Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
