    Abstract: Highly sensitive Surface Enhanced Raman Spectroscopy (SERS) sensors are described in the form of a optical resonator and a metal nanostructure deposited on surface of the optical resonator. In one embodiment the optical resonator is in the form of a photonic crystal, but other optical resonators are contemplated. Examples are described in which the resonant near-fields of a large-area replica molded photonic crystal efficiently couples light from a laser to dielectric-metal “post-cap” nanostructures deposited on the photonic crystal surface by a glancing angle evaporation technique, achieving a high SERS enhancement factor. Other constructions are also contemplated a metal nanostructure formed on a dielectric support deposited on the photonic crystal, including a metallic film deposited over close-packed surface of nanospheres, arrays of metallic nanotriangles, metallic nanorods, metallic nanohelices, arrays of metallic nanospheres, and roughened metal surfaces.

    Abstract: Enhancement of fluorescence emission from fluorophores bound to a sample and present on the surface of two-dimensional photonic crystals is described. The enhancement of fluorescence is achieved by the combination of high intensity near-fields and strong coherent scattering effects, attributed to leaky photonic crystal eigenmodes (resonance modes). The photonic crystal simultaneously exhibits resonance modes which overlap both the absorption and emission wavelengths of the fluorophore. A significant enhancement in fluorescence intensity from the fluorophores on the photonic crystal surface is demonstrated.
