Optical non-linearities usually appear for large intensities, but discretetransitions allow for giant non-linearities operating at the single photonlevel. This has been demonstrated in the last decade for a single optical modewith cold atomic gases, or single two-level systems coupled to light via atailored photonic environment. Here we demonstrate a two-modes giantnon-linearity by using a three-level structure in a single semiconductorquantum dot (QD) embedded in a photonic wire antenna. The large couplingefficiency and the broad operation bandwidth of the photonic wire enable us tohave two different laser beams interacting with the QD in order to control thereflectivity of a laser beam with the other one using as few as 10 photons perQD lifetime. We discuss the possibilities offered by this easily integrablesystem for ultra-low power logical gates and optical quantum gates.
