1.55 μm emission from GaInNAs with indium-induced increase of N concentration

Abstract
GaInNAs/GaAs multiple quantum well (MQW) structures were grown by metalorganic molecular-beam epitaxy (MOMBE). Increase of the N concentration in GaInNAs with increasing In concentration was observed. This trend of enhanced N incorporation for the higher In concentration made it possible to realize long-wavelength emission of 1.55 μm from a GaInNAs/GaAs MQW grown by MOMBE. This result is compared with the previous reports on the growth of GaInNAs alloys and the main factors which lead to the enhanced N incorporation are discussed.
