Paper Abstract

This study aims to designing quantum dot semiconductor optical amplifier (QD-SOA) by amplification without inversion technique in InxGa1-xN/GaN semiconductor quantum dot (nanostructure). To do this, eigen energies and their corresponding wave functions of a Y-type four-level atomic system were obtained by solving of Schrodinger- Poisson equations self-consistently (considering intersublevel transitions) in InxGa1-xN/GaN quantum dot. The principle of quantum optics to obtain dynamic property of quantum dot density matrix elements was employed and investigated the lasing without inversion (LWI) phenomenon in this quantum dot.
