Pulse deformations at guided-mode resonance filters.
A short pulse of light incident on a waveguiding region with a periodic mixture of dielectric materials is shown to experience dramatic changes in its spatial and temporal composition. The reflected and transmitted pulse components experience lateral spread and temporal decompression, which depend on the pulse width, pulse duration, and the structural parameters of the resonant grating.
