The quantum well (QW) transition energies obtained from PR are modeled using a realistic 10-band k·p Hamiltonian that includes tight-binding-based energies and coupling parameters for the N-levels. From this we are able to determine accurately the band structure and thus predict some important device properties for this InGaNAs/GaAs-based laser device | URI: | https://hdl.handle.net/20.500.14279/1371 | ISSN: | 00381098 | DOI: | 10.1016/S0038-1098(02)00772-X | Rights: | © Elsevier Attribution-NonCommercial-NoDerivs 3.0 United States |
