Transparent anomalous dispersion and superluminal light-pulse propagation at a negative group velocity
Anomalous dispersion cannot occur in a transparent passive medium where electromagnetic radiation is being absorbed at all frequencies, as pointed out by Landau and Lifshitz. Here we show, both theoretically and experimentally, that transparent linear anomalous dispersion can occur when a gain doublet is present. Therefore, a superluminal light-pulse propagation can be observed even at a negati...
متن کاملNegative Group Delay and Pulse Compression in Superluminal Pulse Propagation
We systematically study the pulse advance and pulse compression in light propagation through a transparent, anomalously dispersive medium. Using an Argand diagram, we show that pulse compression is the only form of pulse distortion, while other forms of pulse distortion can be eliminated. Experimentally, we implement a dual-band electronic amplifier to measure the negative pulse group delay and...
متن کاملPulse splitting in the anomalous group-velocity-dispersion regime.
We investigate experimentally the role that the initial temporal profile of ultrashort laser pulses has on the self-focusing dynamics in the anomalous group-velocity dispersion (GVD) regime. We observe that pulse-splitting occurs for super-Gaussian pulses, but not for Gaussian pulses. The splitting does not occur for either pulse shape when the GVD is near-zero. These observations agree with pr...
متن کامل“ Superluminal ” Pulse Propagation
With the recent rediscovery of slowand fast-light effects, there has been much interest in pulse propagation phenomena that lead to apparently superluminal pulse transmission. This raises immediate questions about causality and special relativity violations and elicits curiosity about the physical mechanisms responsible for these effects. This thesis will address these issues theoretically and ...
متن کاملNegative Group Velocity Superluminal Propagation in Optical Fibers Using Stimulated Brillouin Scattering
We demonstrated the superluminal propagation at negative group velocity using stimulated Brillouin scattering (SBS) in optical fibers. In the scheme, the Stokes wave is circulated back into the ring cavity for Brillouin lasing to enhance the peak loss. The experiment demonstrated the superluminal light propagation can be realized by increasing the input signal power. The largest time advancemen...
