Abstract
Disclosed are various devices and methods employing photonic crystals to facilitate spatial separation of frequency components of a beam. In one embodiment, an apparatus is provided that includes a preconditioning waveguide facilitating a predefined amount of diffraction of a beam comprising a plurality of wavelengths. A photonic crystal is optically coupled to an output of the preconditioning waveguide. The photonic crystal is configured to spatially separate a plurality of frequency components of the beam.
