Comparing the turn-on dynamics off quantum well and quantum dot lasers

الملخص EN

We investigate the turn –on dynamics of the quantum well and quantum dot lasers under the effect of many parameters on the transient region length up to the initiation of the dc part of the laser signal and the level of the power output at the steady state region .

Our findings are based on two laser models related to the two lasers the first consists of two equations describing the temporal behavior density and photons and the second consists of three equations describing the temporal behavior of occupancies of carriers in the quantum dot QD and wetting layer and photons respectively.
