Abstract: (4776 Views)
In this paper, the optical gain of GaN doubled asymmetric quantum well based laser diode has been investigated. The rate of optical gain in the structure of doubled quantum wells with different structural parameters is considered. The optical gain is obtained for different values of aluminum mole fraction, variations of quantum well thickness and central quantum barrier width from 1 nm to 5 nm. The results of our calculations show that increasing the width of the central barrier and the doubled quantum well will decrease the optical gain.
