Abstract
We report on GaInNAs intermediate layer (IML) structures for improving the lasing characteristics of GaInNAs quantum well (QW) lasers. Either lattice-matched or strained (∼0.65%) GaInNAs IMLs were inserted at GaInNAs/GaAs interfaces. The elongation of the emission wavelength of IML QW structure was observed while maintaining the photoluminescence (PL) emission efficiency in comparison with that of the GaAs barrier QW structure. The elongation of the lasing wavelength of GaInNAs QW lasers without a threshold penalty was also demonstrated by employing a GaInNAs IML. The IML QW exhibited a reduction in the amount of the wavelength blue shift due to postgrowth thermal annealing.
