(color online) Refractometric sensors using lattice plasmons. (a1) and (a2) Subradiative collective modes excited in a suspended nanohole array show extremely narrow peak with FOM reaching 164.[55] (b1) and (b2) Lattice plasmons obtained in gold mushroom arrays, with FOM of ∼108.[56] Reprinted with permission from Copyright 2011 National Academy of Science, Copyright 2013 Nature Publishing Group.
