- Titel:
- Slow light via tunneling induced transparency in quantum well heterostructures
- Abstract:
- 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 [1] in a three level Λ-system by careful engineering of the wave functions [2]. 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 [3].
