Abstract
This paper demonstrates the relationship of the output characteristics and facet reflectivity of superluminescent diode(SLD). according to coupled rate equations. The theoretical calculations show that:(1) The semiconductor laser has a optimum Point of output power facet reflectivity. For a SLD,with the decreasing of facet reflectivity,the power curve slope,maximum output power and spectral modulation depth decrease too.(2) Increasing of back facet reflectivity can increase the output power of SLD and reduce the operation current.(3) Because of the decreasing of the facet reflectivity,the nonuniform of carrier distribution is evident,the backward wave is obviously stronger than forward wave. Finally. as a comparission,the experimental study has been made. The experimental results are well in agreement with theoretical analysis.
