Cavity Effects in Slow-Light Systems

Abstract

Interferometric effects can substantially modify the properties of a slow-light system. A ~100% delay enhancement corresponding to a group velocity of c/12 is achieved in a 2m-long Bi-fiber slow-light system based on Brillouin gain.

Brillouin assisted slow-light enhancement via Fabry-Perot cavity effects

César Jáuregui, Periklis Petropoulos, David John Richardson

We show that the presence of a cavity modifies the behaviour of Brillouin-assisted slow light and can be used to significantly enhance the achievable pulse delays. Moreover, the cavity introduces an additional wavelength dependence into the delay versus gain relationship which can be used to provide an extra degree of control within a slow light system. The degree of delay enhancement depends critically both on the cavity finesse and the Brillouin pump power. Our experiments show that delay enhancements greater than 100% can be obtained accompanied by only relatively modest increases in pulse distortion.

New Approaches to Extending the Performance of Brillouin Based Slow Light Systems

César Jáuregui, Periklis Petropoulos, David John Richardson

We review the development of several new approaches for extending the performance of Brillouin based slow light systems. In particular we describe the use of cavity effects to enhance the achievable delays, gain saturation to decouple the delay and associated signal gain, and the use of tailored pump beams to effect reshaping and retiming of periodic signals.
