    "abstract": "We study the propagation of electromagnetic pulses through photonic bandgap\nmaterials and relate time-domain pulse reshaping to observable transit times.\nFor layered dielectric mirrors we demonstrate how pulse reshaping of slowly\nvarying classical fields results in transit-time delays that are equivalent to\nthe group delay. The time-domain analysis emphasizes the causal origin of\nnegative group delays. We also study an analogous fully-quantized model and\nshow how the same time-domain analysis may be used to interpret observed delays\nof single-photon fields.",
