An age-dependent model of cavity radiation and its detection II. Anti-bunched and thermal characteristics

The model of cavity radiation introduced earlier is analysed further by considering special types of age-specific population growth interpretable in terms of evolution through phases. The model is shown to be versatile enough to admit anti-bunched photon statistics provided the process of spontaneous emission is appropriately modelled. A four-phase model is analysed and the resulting radiation is shown to correspond to the one obtained by the superposition of two independent thermal streams each with a Lorentzian spectrum. © 1993 Indian Academy of Sciences.
