Abstract :
A single-mode multiwavelength EDF laser was realized for the first time in a ring cavity configuration. The laser exhibited flat response over 10 nm, with line spacing of 100 GHz and output power of 10 dBm. The laser was used to test a FFH-OCDMA telecommunication system with a rate of 10 Gchip/s and an equivalent transmission rate of 125 Gbit/s. A strong reduction of beat noise was observed. The results clearly show that a multiwavelength laser source is needed for high data rate FFH-OCDMA systems.
