Superluminal and Slow Light Propagation in a Room
... with Cr ions, and these ions replace the Al3⫹ ions (25), but not all of the ion sites are identical. Namely, 78% of the sites occupied by the Cr3⫹ ions have mirror symmetry (Cs), and the rest have inversion symmetry (Ci) (26). As a result, the absorption cross sections 1, population relaxation time ...

The J0 focusing configuration allows one to construct a system that can continuously switch between these two trapping conditions [14]. It is also observed that J1共x兲 / x correlated fields res ...

The light launched into the core has much lower propagation losses, so that its power remains nearly constant, unless the fiber is very long. The high loss for claddin ...
