Abstract

We report light-beam self-trapping triggered by the pyroelectric effect in an isolated ferroelectric thin film. Experiments are performed in an 8-μm-thick congruent undoped LiNbO3 film bonded onto a silicon wafer. Response time two orders of magnitude faster than in bulk LiNbO3 is reported. The original underlying physics specific of this arrangement is discussed.
