Pulse width reduction in single mode diode lasers via external injection of optical pulses

3 pages, 4 figures.We propose and numerically study a simple scheme to obtain large pulse-width reduction of optical pulses generated by semiconductor lasers. The scheme consists of modulating two single-mode semiconductor lasers coupled through a normal dispersion fiber. The optimal pulse compression is obtained for a particular range of phase delay between the two modulated electrical injection currents. In addition, the optical pulses so obtained have a larger output power and are very close to transform-limited as required for soliton communication systems.This work was supported by the Comisión Interministerial de Ciencia y Tecnología, Project No. TIC93-0744.Peer reviewe
