Abstract
En 中文
We demonstrate how both normal and anomalous dispersion can be realized concurrently for a pair of weak probes in a doubly driven double-ladder configuration with independent and simultaneous control for group velocities of the pair. We have shown both analytically and numerically that, because of electromagnetically induced transparency and a chi((3))-based gain process, a slow-fast light pair can be realized in the same delay element with group indices similar to +/- 10(7) accompanied by gain or relatively small absorption (down to similar to 25%). We also identify parameter regions for realization of concurrent slow-slow and fast-fast light pairs with reduced absorptions. (C) 2011 Optical Society of America
