A dielectric subwavelength resonant waveguide grating was designed and fabricated in order to enhance fluorescence of biomolecules. More than 80 times higher laser-induced fluorescence yield was observed from enhanced green fluorescence protein on the structure when compared to same material on a flat surface.
