Slow light via tunneling induced transparency in quantum well heterostructures

Bernhard Glauber, Petar Tzenov, Christian Jirauschek

We investigate the possibility of slowing down terahertz light via intersubband transitions in quantum well heterostructures. The slow-down effect is achieved via tunneling induced transparency in a three level Λ-system by careful engineering of the wave functions. The inherently short coherence times in such solid state media inevitably leads to strong absorption of the signal, which we propose to compensate for by incorporating a quantum cascade amplifier (QCA) into the system.

Tunneling times in a taut string

Diosdado Villegas, Francisco Antonio Horta-Rangel, Tamé González +3 more

Abstract The mathematical analogy of classical and matter waves can help to teach the elusive subject of tunneling times in undergraduate physics courses. The tunneling of mechanical energy through a taut string is revisited in this paper in order to study tunneling times for this classical system. General properties of the group delay, the dwell time and the interference time are described. Moreover, we explain how to build string arrays with piecewise constitutive parameters that behave like quantum mechanical heterostructures with alternating well and barrier layers. The paradoxical Hartman effect is also analyzed.

Conditions for perfect transmission of quantum particles across layered heterostructures and resonance effects of an auxiliary well potential

Yaroslav Zolotaryuk, Alexander V. Zolotaryuk

We consider the bilayer heterostructure composed of the layer described by a rectangle-like potential and the background layer with an arbitrary potential profile given only by a transmission matrix. The conditions for the perfect (zero reflection) transmission of quantum particles across this structure is derived in the form of two basic equations on the rectangular layer parameters and the distance between the layers. The solution of these equations is analyzed in detail including some special cases and squeezing approximations. The effect of a rectangular well potential on the tunneling of particles with infinitesimally low energy through the background layer is investigated.
