Project description

We aim to develop silicon nitride waveguide structures covered with gold nanodots. The evanescent field of the waveguide will couple to the nanodots and because of this resonant plasmon interaction the enhanced field will result in a stable optical trap. The resulting field will in turn be used for enhanced Raman spectroscopy of the trapped particle.
