    Project Details


    A mathematical model has been derived, describing Colliding-Pulse Mode-Locked (CPM) quantum well lasers. Simulations have been conducted on an InGaAsP laser. Spectral hole burning influences strongly the optical pulse formation. The final pulse width results from a balance between spreading in the gain sections and compression in the absorber section of the CPM laser. Both effects are influenced by ultra fast gain dynamics.
    An alternative approach to generation of ultra short optical pulses is the use of a mode-locked fibre ring laser. Both passive and active mode-locking have been studied by numerical simulations of the Nonlinear Schrodinger equation. Active mode-locking is achieved by the use of a Mach-Zehnder amplitude modulator.
