Stopping light using a transient Bragg grating

We employ a recently developed optical pulse propagation formulation suitable for slow and stopped light regimes to demonstrate light stopping by a (transient) grating coupling in a toy system, which is, however, applicable to a range of wave systems. We study the complete spatiotemporal dynamics, the characteristic timescales, the coupling efficiencies, and the spectral contents of the stopped pulse. Finally, we demonstrate numerically a delay line which surpasses the delay-bandwidth limit.
