A comparative study of the InxGa1-xNyAs1-y/GaAs quantum wells (QWs) for 1.3 mu m laser emission with different x/y concentrations, has been undertaken, for the first time, involving gain characteristics with doping. By considering different x/y concentrations, we present the influence of doping on transparency carrier density, gain properties and spontaneous emission factor of 1.3 mu m InxGa1-xNyAs1-y/GaAs-strained QWs and compare with an equivalent nitrogen-free 1.3 mu m InxGa1-xAs/GaAs laser structure. This study provides useful information for the optimazition of doped InxGa1-xNyAs1-y/GaAs on the basis of 1.3 mu m emission wavelength. (c) 2005 Elsevier B.V. All rights reserved.
