Enhancement of two photon processes in quantum dots embedded in subwavelength metallic gratings

Enhancement of two photon processes in quantum dots embedded in subwavelength metallic gratings

A 20-fold enhancement of two-photon absorption and light upconversion in InAs nanocrystal quantum dots is achieved using resonant local field enhancements in subwavelength nanoslit arrays.
