3.6 Gb/s all laser-diode optical soliton transmission

Abstract
3.6-Gb/s optical soliton transmission using a gain-switched 1.55- mu m distributed-feedback laser diode and a Ti:LiNbO/sub 3/ intensity modulator is demonstrated. An Er/sup 3+/-doped fiber amplifier and a Raman amplifier, both pumped by 1.48- mu m laser diodes, are used for achieving intense optical pulses and fiber-loss compensation, respectively. The intensity-modulation direct-detection optical receiver of a commercial F-1.6 G system is used to measure the bit-error rate.
