Experimental Demonstration of Performance Improvement of 127-Chip SSFBG En/Decoder Using Apodization Technique

Abstract

We present the experimental result of apodiz 127-chip 160-Gchip/s superstructured fiber Bragg grating (SSFBG) en/decoder with Gold code in bipolar phase-shift key coherent time-spreading optical code-division multiple-access system. Compared with uniform SSFBGs, the apodized SSFBG demonstrates the overall performance improvements, including a high reflectivity and a good peak-to-wing ratio of autocorrelation as well as a good bit-error-rate performance.
