Abstract
This paper applies analytical approximations for the luminescence of short period semiconductor superlattices and analyses the low density regime, demonstrating that the theory clearly connects with low density absorption with ratios of oscillator strengths of bound and continuum states as expected from the Elliott formula. A numerical study illustrates in detail the bleaching of higher order bound state. The analytical expressions have potential for systematic studies of controlled excitonic pathways characterized by THz responses.
