|Abstract:||The In-segregation in 7.5-nm Ga1-x′In x′Ny′As1-y′/GaAs single quantum well (QW) is studied theoretically. The nominal (In, N) contents in the QW are chosen to be (0.35, 0.015) and (0.39,0.03) for the emission wavelengths at 1.3 and 1.55 μm, respectively. Muraki's model is used to model the composition profiles in the QWs. In-plane strain, confinement potential, and sub band energy levels of the QW are calculated using multi-band effective mass theory. Our results show that the optical transition energies are approximately constant for the segregation efficiencies smaller than 0.7 in both QWs. © 2006 IEEE.|
