Abstract :
We present the 1.55-μm GaInNAs/GaAs multiple quantum well (QW) heterostructures with GaNAs or GaInNAs barrier and space layer (BSL). An enhancement of photoluminescence intensity and a remarkable reduction of emission linewidth of GaInNAs multiple QWs have been demonstrated by using GaInNAs quaternary BSL, instead of GaNAs BSL. These effects of GaInNAs BSL could be understood in term of the improvement of structural properties of GaInNAs QWs. These results present to us a variable approach to further developing GaAs-based light sources in the telecommunication wavelength range near 1.55 μm.
