Manipulation of Bloch surface waves: from subwavelength focusing to nondiffracting beam
We present a different type of electromagnetic surface wave than a surface plasmon polariton (SPP), called Bloch surface wave (BSW). BSWs are sustained by dielectric multilayers, and therefore they do not suffer from dissipation. Their propagation length is unbeatably long, e.g., over several millimeters. Thanks to this feature, larger integrations of 2D photonic chips are realizable. To do this, 2D optical components and corresponding techniques are necessary to manipulate in-plane propagation of surface waves. We overview recent progresses of the BSW research on manipulation techniques and developed components. Our study will provide a good guideline of the BSW components for users. Keywords: Bloch surface wave (BSW), surface electromagnetic wave, dielectric multilayer, 1D photonic crystal, subwavelength focusing, nondiffracting beam.
