| Abstract(in English) | The dependence of optical properties on crystal orientation is analyzed for long wavelength strained quantum well(QW)lasers.The calculation is based on the multiband effective mass theory which enables us to consider the anisotropy and the non-parabolicity of the valence band dispersions.It is found that the optical gain increases as the crystal orientation is inclined from(001) toward(110).This is due to the reduced valence band density of states.The differential gain is about 1.6 times larger for the(110)-oriented 1.55-μm strained QWs than for equivalent(001)-or iented QWs.It is also shown that the threshold current density in 1.3-μm strained QW lasers decreases to two-thirds of that in the(0 01)-oriented laser as the orientation is inclined away from(001)by 40 to 90 degrees. |
