Faster light with competing absorption and gain
Jon D. Swaim, Ryan T. Glasser
We experimentally investigate the propagation of optical pulses through a fast-light medium with competing absorption and gain. The combination of strong absorption and optical amp…

Causality and information transfer in simultaneously slow- and fast-light media
Jon D. Swaim, Ryan T. Glasser
We demonstrate the simultaneous propagation of slow- and fast-light optical pulses in a four-wave mixing scheme using warm potassium vapor. We show that when the system is tuned su…
