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 $\sim$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.
