This study investigates the basic principles of quantum well semiconductor laser design optimization and the current pumping requirements for generating optical pulses by gain switching. The experiment finds that there exist optimal values of optical confinement factor, resonator length, and current pulse amplitude for achieving maximum peak output power. Moreover, the study reveals that the optimal resonator length strongly depends on the target pulse width.
We have studied the basic principles of quantum well semiconductor laser design optimization and current pumping requirements for generating optical pulses with a defined width and maximum peak power by gain switching. It is shown that for a given pulse width there exist a set of optimal values of optical confinement factor, resonator length and current pulse amplitude, that ensure maximum peak output power. It is determined that the maximum output power is achieved when the optical confinement factor is as low as possible, so that the pulse width does not exceed the target value. The optimal resonator length is found to strongly depend on the target pulse width.
