Near-field study of dielectric surface lens

In this work, we design, fabricate and experimentally characterize a surface structured lens within an ultra thin polymer layer deposited on a Bloch Surface Waves (BSWs) suspended dielectric platform. The near-field (SNOM) measurements demonstrate that the lens is able to manipulate the propagation of the surface waves. Experimental result shows good agreement with the simulation calculated using the finite difference time-domain (FDTD). This work opens a way to realize surface structured integrated all-optical systems and the study of fundamental optical phenomena.
