Peaking of Optical Pulses in Vertical-Cavity Surface-Emitting Lasers with an Active Region Based on Submonolayer InGaAs Quantum Dots

Vertical-cavity surface-emitting lasers with an active region based on submonolayer InGaAs quantum dots with an oxide-aperture diameter of similar to 1 mu m have been studied. It is established that peaking of the output optical pulses to 50-100 ps can be achieved by pumping these lasers with 10-100 ns electric pulses at a repetition frequency of 10-100 kHz.
