Abstract
We report the observation of an optical Wannier-Stark ladder in a linearly chirped Moiré grating, written in the core of an optical fiber. The use of photons avoids the strong excitonic interactions encountered in more traditional experiments using charge carriers in semiconductors.Keywords
