文摘Using a set of traveling wave rate equations,a superluminescent diode with a low facet reflectivity is studied. Analytical expressions of the distributions of carrier density,forward- and backward-propagating photon densities,and gain are obtained at different facet reflectivities.It is shown that the high nonuniform carrier distribution is evident in the case of low facet reflectivity.The results can serve as useful guides in understanding emission mechanism of superluminescent diodes.
