Abstract(in English) We fabricated GaInNAs lasers by using impurity-reduced GS-MBE. Aluminum, one of residual impurities, enhances three dimensional growths of GaInNAs, which should be reduced. The material of GaInP was used as the cladding layers for eliminating Aluminum. The threshold current density for this laser is about half of that for lasers that contained Aluminum. The threshold current for the GaInNAs RWG laser is almost the same range as that for the conventional long wavelength laser. However, threshold current density and threshold current for GaInNAs lasers is different from those for GaInAs lasers. The same difference is observed for relaxation oscillation frequency, It indicates the qualities of GaInNAs crystallization should be improved with the exception of reduction in residual impurities.
