Abstract

Security enhancement of stealth channel by combining time-domain spectral phase en/decoding (SPE/D) OCDMA scheme and group velocity dispersion is proposed and experimentally demonstrated. The time-domain spectral phase encoded OCDMA signal, which utilizes a linearly chirped fiber Bragg grating for pulse broadening and a high-speed phase modulator for SPE, has been stealth transmitted over a public wavelength-division-multiplexing network. Error-free transmission (bit-error rate < 10(-9)) has been achieved for both the public and stealth channel with 32-chip 40-Gchip/s gold codes.
