On "incorrectness" of the rate equation for photon density of semiconductor lasers

The authors of works [1, 2] published in Quantum Electronics assert that the rate equation for photon density with a term taking into account the contribution of spontaneous emission to the laser mode is erroneous (i.e., the spontaneous term should be excluded from consideration) and criticise works...

Description
Summary:The authors of works [1, 2] published in Quantum Electronics assert that the rate equation for photon density with a term taking into account the contribution of spontaneous emission to the laser mode is erroneous (i.e., the spontaneous term should be excluded from consideration) and criticise works [3, 4]. In the present work, we analyse previously published papers and show that the necessity of taking into account the contribution of spontaneous emission to the laser mode follows from the quantum-mechanical rate equation for semiconductor lasers. The results obtained in [1, 2] are analysed.
