Abstract
We time resolve the dynamic response of InGaAsP quantum-well semiconductor diode lasers after injection of a femtosecond pulse, using ultrafast upconv ersion. The injection of a single off-resonant pulse leads to a very fast g eneration of picosecond 'dark pulses', which then generate bright pulses ag ain, leading to dark-pulse-bright-pulse oscillations with a change-over per iod of 500 ps. We suggest that nonlinear gain compression causes these osci llations. (C) 1999 Elsevier Science B.V. All rights reserved.
