Plasmonics and metamaterials using nanoparticles

SeokJae Yoo

When chiral emitters couple to resonance modes of optical resonators, the decay rate of chiral emitters changes significantly. This research discovered the chiral Purcell effect to explain the principle of the modified decay rate of chiral emitters. To support the chiral Purcell effect, I also suggested designs of resonators, such as the double fishnet structure and the nano-hole metasurface.
