Electromagnetically Induced Transparency in Ensembles of Classical Oscillators

Abstract

We develop a classical model of the parametric effect of electromagnetically induced transparency (EIT) within the line of resonance absorption of an electromagnetic wave in the medium--an effect initially discovered for a quantum three-level system. On the basis of this model, the EIT effect for electromagnetic waves at frequencies of the electron-cyclotron resonance in a cold plasma is considered. Similar to the analogous quantum scheme, the EIT window in the classical model is characterized by group deceleration of the reference electron-cyclotron wave.

Magnetically Induced Transparency and Its Application as an Accelerator

“…Recently it was theoretically found that a magnetized plasma can be made transparent to a right-hand polarized wave (probe) at the cyclotron frequency in the presence of strong pump wave which is detuned by the plasma frequency [1][2][3]. This is a classical analogy of the quantum electromagnetically induced transparency (EIT) [4,5].…”

A study of undulator induced transparency of magnetized plasma in the linear regime

“…An electromagnetically induced transparency (EIT) [1], the well-known quantum phenomenon in contemporary nonlinear optics, has a classical counterpart in plasma physics, an effect of the magnetized plasma transparency at the cyclotron frequency [2,3]. This phenomenon is caused by an appearance of a transparency band within the resonance absorption zone in the presence of either a strong electromagnetic wave or a magnetostatic undulator, allowing propagation of electromagnetic waves in the normally opaque medium.…”

Controllable Kerr Nonlinearity via Incoherent Pump Fields in Semiconductor Quantum Wells

“…There are many interesting phenomena in quantum optics and atomic physics, induced by quantum coherence and quantum interference. Examples include electromagnetically induced transparency (EIT) [1,2,3]], coherent population trapping (CPT) [4], cancelation of spontaneous emission [5], superluminal and subluminal light propagation [6,7], lasing without inversion [8,9], and so on. The effect of electromagnetically induced transparency (EIT) has led to many interesting nonlinear optical phenomena.…”
