The Regulation and Control of Electromagnetically Induced Transparency and Absorption in an Optical-radio Two-photon Coupling Configuration

The frequency-sensitive optical response due to two-photon resonance of electromagnetically induced transparency (EIT) in a tunable band structure of an EIT-based layered medium is considered. The unit cells of this periodic layered structure are composed of dielectric (e.g., GaAs) and EIT atomic vapor. The frequency-sensitive behavior of controllable reflectance and transmittance depending on the external control field can be applicable to new device design (e.g., it can serve as the fundamental working mechanism for photonic switches and photonic logic gates). Some two-input logic gates (e.g., OR and NAND gates) are designed based on the present effect of sensitive switching control that results from the two-photon resonance.

Induced Transparency

Since a two-level resonant atomic system can be simulated by a simple circuit, three- and four-level electromagnetically induced transparency (EIT) that occur due to light-atom interaction can find its classical counterpart in circuit analog. As the optical response of an EIT atomic medium (including atomic vapors and semiconductor-quantum-dot dielectrics) can be controlled via tunable quantum interference induced by applied external control fields, in the scheme of circuit analog, such a controllable manipulation is achieved via capacitor coupling, where two loops are coupled by a capacitor that can represent the applied control fields in atomic EIT. Both numerical simulation and experimental demonstration of three- and four-level EIT were performed based on such a scenario of circuit analog. The classical “coherence” relevant to quantum interference among transitions pathways driven by both probe and control fields in EIT atomic systems has been manifested in the present circuit analog of EIT.

Dephasing Rate

In this paper, we investigated the realization of electromagnetically induced transparency (EIT) in a rectangular quantum dot (QD) with a single electron in the presence of probe and control laser fields. The lowest three levels of the confined electron that form ladder and V configuration were chosen. We discussed the dependence of density matrix elements for ladder configuration and for V configuration on detunings of the probe field for various values of quantum dot dimensions. This dependence is discussed for both cases, at cryogenic temperatures when spontaneous emission dominates the relaxation mechanism and at room or higher temperatures when dephasing rate cannot be neglected.
