Title: Bloch Surface Waves: A Platform for 2D Integrated Optics
Abstract:
Nano-photonics, where optical structures can manipulate light at the sub-wavelength scale, is making important advances towards optical communications, imaging and sensing. A novel platform suitable for fundamental investigations of light propagation through micro- and nanostructures will be discussed. This platform is based on a dielectric multilayer that sustains Bloch surface waves (BSWs). BSWs are electromagnetic modes which may take place at the interface between a truncated 1D photonic crystal structure and a homogeneous dielectric medium. The results obtained confirm the possibility of developing a robust multilayer platform for 2D integrated optics.
