摘要: We report on the observation of Bloch oscillations in light transport through periodic dielectric systems. By introducing a linear refractive index gradient along propagation direction optical equivalent Wannier-Stark ladder was obtained. were observed as time-resolved transmission, direct analogy to electronic conducting crystals where is obtained via an external electric field. The oscillatory behavior excellent agreement with transfer matrix calculations.
