  • Abstract
    The effect of detuning the Bragg wavelength for picosecond pulse generation in GaInAsP distributed feedback (DFB) lasers is investigated using the gain switching method. The authors have observed that the pulse width is reduced in a detuned DFB laser, in which the differential gain is enhanced through detuning the Bragg wavelength λB from the gain peak to a shorter wavelength by 100 Å. This result demonstrates the significance of the differential gain for short pulse generation
