Theoretical analysis of spatial current turn-on dynamics in high-power AlGaAs/GaAs laser-thyristors with an optical feedback

A numerical study of laser-thyristors spatial current turn-on dynamics is carried out. It is shown that the presence of optical feedback can reduce the maximum current density in the current filament and local heating in the structure. This effect is present when the photogeneration rate in the p-ba...

Summary:A numerical study of laser-thyristors spatial current turn-on dynamics is carried out. It is shown that the presence of optical feedback can reduce the maximum current density in the current filament and local heating in the structure. This effect is present when the photogeneration rate in the p-base of the laser-thyristor is comparable to the impact ionization rate.
