Nonlinear optical processes using electromagnetically induced transparency

Optical properties and optimization of electromagnetically induced transparency in strained InAs/GaAs quantum dot structures

“…22,23 By virtue of the Kramers-Krönig relations a dip in absorption is accompanied by a large positive slope of the refractive index which translates into a reduced group velocity in vicinity of the resonance. Experimental realization of EIT in semiconductor structures has been achieved for the case of quantum wells Refs.…”

A macroscopical entangled coherent state generator in a V configuration atom system

“…(16)) and the average total photon number (Eqs. (12) and (13)) of our state. Here, the positive sign has been chosen for Eq.…”

“…These include correlated spontaneous emission laser (CEL) [10], lasing without inversion [11] and electromagnetically induced transparence [12] etc.. It has been known that two cavity modes can be entangled when they interact with three-level atoms [10,13] and atomic coherence plays an essential role in this entanglement generation [14,15].…”

Controlling laser spectra in a phaseonium photonic crystal using maser

“…Such systems can exhibit quantum coherence and interference effects, e.g., enhanced nonlinear effects [1], electromagnetically induced transparency (EIT) [2][3][4], giant Kerr nonlinearity [5][6][7], lasing without inversion [8][9][10], efficient nonlinear frequency conversions [11,12], coherence Raman scattering enhancement via maximum coherence in atoms [13] and molecules [14], enhanced lasing [15,16], coherent Raman umklappscattering [17], photodesorption [18] to name a few. Recently quantum coherence effects has been applied to a new domain on plasmonics and shown to benefit nanophotonics [19,20].…”
