Abstract :
The transient behavior of a field-effect GaAs laser diode is modeled under a controlled carrier distribution in the central ( Gamma ) and satellite (S) valleys. The carrier distribution control is achieved by modulating the applied electric field which heats carriers to energies higher than 0.38 eV for Gamma to S scatterings. The numerical analysis of the rate equations shows that picosecond optical pulses can be produced.<>
