1 Dec 2007 | | Abstract: | We present a general scheme to determine the loss-free adiabatic
eigensolutions (dark-state polaritons) of the interaction of multiple probe
laser beams with a coherently driven atomic ensemble under conditions of
electromagnetically induced transparency. To this end we generalize the
Morris-Shore transformation to linearized Heisenberg-Langevin equations
describing the coupled light-matter system in the low excitation limit. In
particular a closed-loop double-V scheme is considered where two
counter-propagating control fields generate a quasi stationary pattern of two
counter-propagating probe fields, so-called stationary light. It is shown that
contrary to previous predictions there exists a single unique dark-state
polariton that obeys a simple propagation equation. In the case of a simple
lambda-type coupling scheme the generalized Morris-Shore transformation
reproduces the dark-state polariton solutions of slow light. | | Source: | arXiv, 0712.0060 | | Services: | Forum | Review | PDF | Favorites | |
