  In this letter, we report the first experimental observation of a photonic
hook - a new type of near field curved light generated at the output of
dielectric cuboid with broken symmetry having dimensions comparable to the
electromagnetic wavelength. The radius of curvature associated with the
generated photonic hook is smaller than the wavelength used while its minimum
beam-waist is about 0.44 lamda. This represents the smallest radius of
curvature ever recorded for any alectromagnetic beams.
