Abstract

Systems and methods employ a layer having a pattern that provides multiple discrete guided mode resonances for respective couplings of separated wavelengths into the layer. Further, a structure including features shaped to enhance Raman scattering to produce light of the resonant wavelengths can be employed with the patterned layer.
