Abstract

We describe and experimentally demonstrate the conversion of light propagating in a medium of Rb atoms into an excitation with localized, stationary electromagnetic energy, which can be held and released after a controllable interval.

Armazenamento e distribuição de pulsos ópticos com conversão em múltiplos comprimentos de onda

Wellington C. R. Nascimento

Based in the effect of the Electromagnetically Induced Transparency (EIT) and the storage of light in atomic medium, we propose multi-wavelength optical pulse conversion. Starting from coupled Maxwell-Bloch equations, we simulate the propagation of the optical pulses resonant with electric dipole transition in the atomic system. Considering a three level Λ-type atomic system, we investigate the effect of the storage of light under EIT and we approach the wavelength conversion process using a double-Λ system. Generalizing the process for a triple-Λ system, we show the possibility of multi-wavelength conversion of a field previously stored in the atomic system. In this last case, we simulate the propagation of the six fields interacting resonantly, where three of the fields are called control fields and others are probe fields. First only two fields are incident in the medium, a probe Field and a control field, thus we establish the EIT regime. When we turn off the control field, the probe field is stored in the medium as a collective excitation between the lower energy levels which corresponds to a dark state of the atomic system. Depending on the choice of the control field which is turned on, we show that it is possible to store a field for a given a time and later to release it in differents wavelengths.

Quantum manipulation of two-color stationary light: Quantum wavelength conversion

S. A. Moiseev, Byoung Seung HAM

We present a quantum manipulation of a traveling light pulse using electromagnetically induced transparency-based slow light phenomenon for the generation of two-color stationary light. We theoretically discuss the two-color stationary light for the quantum wavelength conversion process in terms of pulse area, energy transfer, and propagation directions. The condition of the two-color stationary light pulse generation has been found and the quantum light dynamics has been studied analytically in the adiabatic limit. The quantum frequency conversion rate of the traveling light is dependent on the spatial spreading of the two-color stationary light pulse and can be near unity in an optically dense medium for the optimal frequencies of the control laser fields.

Storing and releasing light in a gas of moving atoms

Gediminas Juzeliūnas, M. Mašalas, Michael Fleischhauer

We propose a scheme of storing and releasing pulses or cw beams of light in a moving atomic medium illuminated by two stationary and spatially separated control lasers. The method is based on electromagnetically induced transparency but in contrast to previous schemes, storage and retrieval of the probe pulse can be achieved at different locations and without switching off the control laser.
