Paper Abstract

A novel type of laser diodes and amplifiers based on asymmetric quantum-well heterostructures having a set of active layers of different thickness and/or compositions has been considered. In contrast to ordinary laser heterostructures, for such modified quantum-well systems, it is possible to change the gain spectrum in a wide range and to control the set of definite amplification frequencies due to the selecting of the width and composition of quantum wells and barrier regions and of their doping and arrangement as well. New heterostructure schemes for tunable spectrum light-emitting sources have been proposed.
