A nonlinear optical plasmonic crystal is designed by integrating an organic active medium with a large optical nonlinearity into a conventional plasmonic nanostructure. The surface plasmon-enhanced third harmonic generation (THG) from the metal–organic hybrid plasmonic crystal is experimentally demonstrated. The metal–organic hybrid configuration provides new concepts to develop novel nonlinear optical devices with subwavelength electromagnetic-wave confinement.
