Slow light with flat or offset band edges in few-mode fiber with two gratings

Sukhorukov, Andrey; Handmer, C.J; de Sterke, C Martijn; Steel, Michael J


We consider mode coupling in multimode optical fibers using either two Bragg gratings or a Bragg grating and a long-period grating. We show that the magnitude of the band edge curvature can be controlled leading to a flat, quartic band-edge or to two band edges at distinct, nonequivalent k-values, allowing precise control of slow light propagation.
