NM07–Design and Analysis of Slow Light Device based on Double Quantum Dots Tunneling Induced Transparency

Slow light Transparency window can be achieved with the help of Electromagnetically Induced Transparency (EIT) method and Tunneling Induced Transparency (TIT) method accompanied by observing tunneling effect between InAs quantum dot structure with energy gap of 0.35 eV and a thin layer of GaAs potential barrier with energy gap of 1.42 eV. By investigating different parameters such as group velocity and Slow Down Factor (SDF) coefficient at different detuning frequencies, we have obtained an improved design in tunneling and identifying some better conditions. Under TIT condition, the SDF parameter has improved to the amount of 3.2×10⁶.
