Light propagation in a 1D medium of high optical density — •Roman Sulzbach and Reinhold Walser — Institut für Angewandte Physik, TU Darmstadt, Schlossgartenstr. 7, 64289, Darmstadt

Electromagnetically induced transparency (EIT) has found many applications in quantum optics, since its experimental demonstration in 1990 [1]. Recently, it was possible to demonstrate EIT and the related effects of slow and stationary light pulses in a hollow fiber containing a thin medium of cold Rubidium atoms [2]. These hollow fibers have a diameter of 7 µm and a length of 10 cm. Therefore, this system represents a one-dimensional medium of high optical density.

We use Maxwell-Bloch theory to simulate the pulse propagation of the probe-beam inside this fiber. This leads to a paraxial Schrödinger-equation as well as to corrections. We will present results of numerical simulations of this strongly interacting light-matter system.
