Band structures and optical gain of strained GaAs[sub x]P[sub 1−x−y]N[sub y]/GaP quantum wells

In the framework of effective mass Hamiltonian of semiconductor quantum well structures and band anticrossing model, we investigated the band structures of fully strained GaAsxP1−x−yNy /GaP quantum wells. The GaAsxP1−x−yNy could be widely modified to be direct-band gap or indirect-band gap by changing the mole fraction of As and N in the well layer. We found that an increase in the N mole fraction in the well layer increases the TE mode optical gain very slightly.Published versio
