Abstract:
The propagation of coherent and partially coherent light pulses through a one-dimensional photonic crystal ( 1DPC ) is investigated. The dependence of the evolution of the pulses inside the 1DPC on incident angles and the effect of the coherence of the pulses on the propagation properties are discussed. The evolution of a pulse inside the 1DPC is affected by the coherence of the pulse. As the coherence decreases, superluminal proprogation changes to subluminal propagation.

Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...
