Double Resonance Self-induced Transparency
An analytic solution is found for SIT with two co-propagating pulses which are doubly resonant with two transitions sharing a common excited state. The pulse shapes are the usual hyperbolic secants, but the areas are not 2n. This solution satisfies the atomic equations exactly for all detunings and arbitrary relative amplitudes for the two pulses. The field equations, however, place extra restr...
متن کاملMixed electromagnetically and self-induced transparency.
We show that application of self-induced transparency (SIT) solitons as a driving field in V-type electromagnetically induced transparency (EIT) leads to ;;mixed induced transparency' (MIT) that nicely combines the best features of both SIT and EIT.
متن کاملUltrashort self-induced transparency plasmon solitons.
We study the interband self-induced transmission of surface plasmon polaritons in a gold film surrounded by an external Kerr medium. We model the optical propagation by using a version of the generalized nonlinear Schrödinger equation for the field envelope coupled to Bloch equations for valence electrons of gold, predicting self-induced transparency of ultrashort plasmon solitons with a pulse ...
متن کاملQuantum Theory of Self-Induced Transparency
It is known that classical electromagnetic radiation at a frequency in resonance with energy splittings of atoms in a dielectric medium can be described using the classical sineGordon theory. In this paper we quantize the electromagnetic field and compute some quantum effects by using known results from the sine-Gordon quantum field theory. In particular, we compute the intensity of spontaneous...
متن کاملQuantum self-induced transparency in frequency gap media
– We study quantum effects of light propagation through an extended absorbing system of two-level atoms placed within a frequency gap medium (FGM). Apart from ordinary solitons and single-particle impurity band states, the many-particle spectrum of the system is shown to contain massive pairs of confined gap excitations and their bound complexes—gap solitons. Quantum gap solitons propagate with...
