Abstract :
The spontaneous emission rate of distributed feedback semiconductor lasers with partially reflecting facets is analysed using the Green function approach. It is found that this rate depends on both the facet reflectivities and the coupling coefficient. The linewidth of DFB lasers is evaluated by including this dependence.
