Abstract
A method, system and article of manufacture for amplification of light for surface enhanced Raman spectroscopy. The method and system include a source of input light, a grating with grooves therein, a nanoparticle array disposed in the grooves with the nanoparticles and grating having a variety of selectable parameters. The combination of the nanoparticles and selected characteristics, including generating hot spots, and the features of the grating enable enhanced amplification of the input light signal to provide an output Raman signal of greatly increased intensity for Raman spectroscopy.
