Experimental demonstration of enhanced slow and fast light by forced coherent population oscillations in a semiconductor optical amplifier
15 July 2010
We experimentally demonstrate enhanced slow and fast light by forced coherent population oscillations in a semiconductor optical amplifier at gigahertz frequencies. This approach is shown to rely on the interference between two different contributions. This opens up the possibility of conceiving a controllable rf phase shifter based on this setup.
