摘要:

We attribute the single longitudinal mode operation of some Er‐doped 1.5‐&mgr;m InGaAsP lasers, observed here, to inhomogeneities in the active layer resulting from the Er. These results do not rule out the possibility of gain narrowing by the Er when Er is properly incorporated in the active layer.
