“…The dispersion law of the BSWs can be chosen in wide spectral range from UV to IR by changing the photonic crystal parameters [6,7]. High sensitivity of the BSWs to boundary conditions provides the possibility to use them as bio-and gas sensors [8][9][10][11][12][13]. Another promising area of application of the BSWs is the development of photonic devices for optoelectronic integrated circuits.…”

Abstract:The review considers the influence of Bloch surface waves on the optical and magneto-optical effects observed in photonic crystals; for example, the Goos-Hänchen effect, the Faraday effect, optical trapping and so on. Prospects for using Bloch surface waves for spatial light modulation, for controlling the polarization of light, for optical trapping and control of micro-objects are discussed.

“…However, despite their remarkable performances, the resolution obtainable in resonance angle shift and the sensitivity of the SPR technique is limited by resonance width, which, in turn, depends on the large optical absorption induced by metallic layer [12,13]. Moreover, the local heating associated to such losses leads to high dissipations in the fluid medium carrying the analyte, inducing unwanted vortices in the carrier flow and eventually damages in the biological material [14].…”

In this paper, experimental evidences about the resonance phenomena in a negative 2D photonic crystal are shown. Localized plasmon-like modes and guided mode resonances are detected in the reflectivity spectrum of a photonic crystal slab irradiated with out-of-plane incident radiation. The strong confinement of the radiation, in addition to the field enhancement, make photonic crystals a very appealing alternative to plasmonic substrates, avoiding the limits of absorption losses in metals.

“…A dielectric multilayer platform, sustaining BSWs, has been studied extensively for many applications, such as sensing and in-plane optics [3][4][5]. The modes propagating on the multilayer interface decay exponentially inside the multilayers due to the presence of the photonics band gap [1].…”

Bloch Surface Waves Using Graphene Layers: An Approach toward In-Plane Photodetectors

et al. 2018

A dielectric multilayer platform was investigated as a foundation for two-dimensional optics. In this paper, we present, to the best of our knowledge, the first experimental demonstration of absorption of Bloch surface waves in the presence of graphene layers. Graphene is initially grown on a Cu foil via Chemical Vapor Deposition and transferred layer by layer by a wet-transfer method using poly(methyl methacrylate), (PMMA). We exploit total internal reflection configuration and multi-heterodyne scanning near-field optical microscopy as a far-field coupling method and near-field characterization tool, respectively. The absorption is quantified in terms of propagation lengths of Bloch surface waves. A significant drop in the propagation length of the BSWs is observed in the presence of graphene layers. The propagation length of BSWs in bare multilayer is reduced to 17 times shorter in presence of graphene monolayer, and 23 times shorter for graphene bilayer.
