Abstract

We propose and experimentally demonstrate a 2.5-Gb/s two-user optical-code-division-multiple-access (OCDMA) system with a novel time domain spectral phase encoding scheme and variable-bandwidth spectrum shaper (VBS)-based spectral phase decoder. The spectral phase encoded OCDMA signal is generated by using a pair of dispersive fibers with opposite dispersion and a high speed phase modulator with rapid programmable 8-chip, 20 Gb/s optical code patterns in time domain, and spectrally decoded using a VBS with high controlling precision of amplitude and phase. A total of 2.5-Gb/s time domain spectral phase encoded on-off-keying OCDMA signal data has been successfully transmitted over 34 km fiber with error-free. (C) 2011 Wiley Periodicals, Inc.
