Interband optical investigation of Bloch oscillations in semiconductor superlattices
The experimental observation of Bloch oscillations in solids was long thought to be out of experimental reach. The invention of the semiconductor superlattice has changed this situation decisively. Transport experiments performed in the past two decades have given indirect evidence for the existence of Bloch oscillations. Recently, it has been possible to directly observe Bloch oscillations in ...
متن کاملOptical analogue of electronic Bloch oscillations.
We report on the observation of Bloch oscillations in light transport through periodic dielectric systems. By introducing a linear refractive index gradient along the propagation direction the optical equivalent of a Wannier-Stark ladder was obtained. Bloch oscillations were observed as time-resolved oscillations in transmission, in direct analogy to electronic Bloch oscillations in conducting ...
متن کاملSurface acoustic BLOCH oscillations, the Wannier-Stark ladder, and Landau-Zener tunneling in a solid.
We present the experimental observation of Bloch oscillations, the Wannier-Stark ladder, and Landau-Zener tunneling of surface acoustic waves in perturbed grating structures on a solid substrate. A model providing a quantitative description of our experimental observations, including multiple Landau-Zener transitions of the anticrossed surface acoustic Wannier-Stark states, is developed. The us...
متن کاملac-Field-controlled Anderson localization in disordered semiconductor superlattices.
An ac field, tuned exactly to resonance with the Stark ladder in an ideal tight binding lattice under strong dc bias, counteracts Wannier-Stark localization and leads to the emergence of extended Floquet states. If there is random disorder, these states localize. The localization lengths depend nonmonotonically on the ac field amplitude and become essentially zero at certain parameters. This ef...
متن کاملBloch oscillations and Wannier-Stark localization in semiconductor superlattices
Ever since the initial applications of quantum mechanics to the dynamics of electrons in solids, the analysis of Bloch electrons moving in a homogeneous electric field has been of central importance. By employing semiclassical arguments, in 1928 Bloch [1] demonstrated that, a wave packet given by a superposition of single-band states peaked about some quasimomentum, h̄k, moves with a group veloc...
