Abstract
A formal proof of the stability of a widely applicable form of the laser diode rate equations is presented. The conditions under which this proof holds provide guidance to designers and modellers of laser diodes in the identification of ranges of parameter values that preserve stability. The proof requires that there is some non-zero threshold for gain in order to guarantee stability. Laser models incorporating Purcell enhancement factors are found to be stable for all physically allowed values of the factor. © 2009 IOP Publishing Ltd.
