Abstract

In this paper, we present a coherent direct sequence OCDMA en/decoder based on Linearly Chirped Superstructured Fiber Bragg Gratings (LC-SSFBGs) with improved energetic efficiency up to 20 dB. In addition, our simulations show that the introduction of chirp improves the autocorrelation to cross correlation and the autocorrelation to wings time gated ratios for both low and high reflective regimes.
