Atoms trapped above the surface of optical nanofibers can exhibit strong coupling to fiber-guided light which can lead to non-linearities in the transmission of resonant light. We study this process experimentally with laser-cooled Cesium atoms stored in a two-color nanofiber-based dipole trap and analyse the transmission of a resonant probe field through an atomic ensemble with large optical depth. One goal is to investigate non-linear photon-transport through the ensemble as recently suggested by Mahmoodian et al. [1]. There, resonant photon pairs are converted into off-resonant pairs with opposite detuning relative to the resonance. These are then transmitted through the ensemble while single photons are extinguished due to linear absorption leading to bunching in the light exiting the ensemble. This may open a new avenue toward generating non-classical states of light.
