Improvement of performance in FFH-OCDMA systems by using strong apodized fiber Bragg gratings

Autor: Catalina A. Ramirez, Pedro Torres, J. I. Marulanda

Publikováno v: SPIE Proceedings.

This paper shows simulations of an all-fiber fast optical code division multiple access communications system (OCDMA), using strong apodized fiber Bragg gratings (FBGs) arrays as passive encoding-decoding devices. Auto and cross-correlation functions
