Supercontinuum from a feedback configuration

Optical supercontinuum, broadband light with good spatial coherence, finds many uses. Currently it is typically produced by passing short light pulses through a piece of photonic crystal 'holey' fiber, thereby widening the spectrum by nonlinear interactions. Here we report on a scheme which uses a fiber resonator for optical feedback to enhance the effect. This approach provides additional degrees of freedom for optimization, and it reduces power requirements.
