Abstract :
We present, for the first time, a CW 1.5 μm range GaInNAs(Sb) laser with threshold current density comparable to 1.3 μm range GaInNAs laser. The lasers used in this study were conventional ridge waveguide devices. The devices were grown by solid source molecular beam epitaxy (MBE) with nitrogen supplied rf plasma cell. The active region was nominally based on a QW with room temperature (RT) photoluminescence (PL) at 1.43 μm and line width of 29.7 meV.
