Using numerical simulations, we report the observation of a new effect—a spectral Talbot-like effect—in one-dimensional photonic bandgap structures, particularly sampled chirped fiber Bragg gratings. We derive the general conditions for which spectral Talbot-like phenomena, namely, integer and fractional spectral self-imaging, can be observed and relate them to the physical grating parameters.
