Such multiple (re)absorption/(re)emission cycles result in a certain population of "recycled photons" concentrated inside the semiconductor. Consequently, an efficient PR effect provides another degree of freedom to control the photon and carrier densities in a semiconductor [2] and hence a way to tailor-made its optoelectronic properties. [3, 4] Demonstrated applications include solar cells, light-emitting diodes, or optical modulators. [2] In this context, PR has been recently claimed in
