Description

It is demonstrated that the micro-photoluminescence spectrum of a single InAs/GaAs quantum dot undergoes considerable changes when the primary laser excitation is complemented with an additional infrared laser. The dependence of the observed phenomenon on the powers of the two lasers and the temperature has been studied and is in consistence with the model proposed

Abstract (Russian)

Показано, что микрофотолюминесцентный спектр одиночной InAs/GaAs квантовой ямы испытывает значительные изменения в тех случаях, когда первичное лазерное возбуждение сопровождается возбуждением инфракрасного лазера. Исследуется зависимость наблюдаемого явления от мощностей обоих лазеров и температуры. Полученные результаты подтверждают предложенную модель
