Abstract
A system and method for quantizing a photonic signal involves passing the photonic signal through a photonic crystal. The photonic crystal has localized defects for splitting the photonic signal into a plurality of quantized photonic components and for directing the quantized photonic components to a set of optical detectors. A digital conversion of the photonic signal can occur by performing a threshold comparison of the quantized components, either in the electrical domain through comparators or in the optical domain through optical limiters.
