Abstract
Superluminal propagation at negative group velocity was demonstrated in a highly nonlinear fiber embedded in a Brillouin laser ring cavity. A maximum advancement of 369 ns and strong Stokes lasing power of 482 mW were achieved when the cavity was pumped with a 1 MHz sinusoidal wave modulated signal at power level of 1 W. The frequency dependence of fast light in this fiber ring cavity was examined with modulation frequencies of 1 kHz to 15 MHz. a maximum fractional advancement of 0.54 was achieved at 10 kHz and a maximum negative group index of - 9480 was demonstrated at 1 kHz.
