Özet

The optical analogue to electromagnetically induced transparency (EIT) is modeled for two separate systems with the same formalism and the spectral characteristics together with the generated group delay are compared. First system is a coherently coupled high-Q multi-cavity array which represents the classical EIT and is limited by the finite broadening of the cavity and the second one is a single embedded quantum dot (QD) cavity system, a cavity-QD EIT, that depends on both QD broadening and cavity properties. Similar spectral characters have been observed for both systems but the former generated theoretically two times higher group delays.
