“…Nevertheless, their consequences on GH and IF shifts are not yet fully explored. In particular, while the impact of the large derivative of the phase of the reflection coefficient for GH shift value has been previously studied both numerically [15] and experimentally [16], the impact for IF shifts has not yet been explored.…”

We investigate the effect of a surface plasmon resonance on Goos-Hanchen and Imbert-Fedorov spatial and angular shifts in the reflection of a light beam by considering a three-layer system made of glass, gold and air. We calculate these spatial and angular shifts as a function of the incidence angle showing that they are strongly enhanced in correspondence of the resonant angle. In particular, we find giant spatial and angular Goos-Hanchen shits for the p-wave light close to the plasmon resonance. We also predict a similar, but less pronounced, resonant effect on spatial and angular Imbert-Fedorov shifts for both s-wave and p-wave light.PACS numbers: 42.25. Hz, 78.20.Bh It is now established [1][2][3][4][5][6][7] that there are four shifts that can happen when light is reflected. These are the two longitudinal shifts (spatial and angular GH shifts) and the two transverse shifts (spatial and angular IF shifts). Recently, the predicted GH spatial shift [8] of a light beam on a metallic mirror has been measured [9], showing a good agreement with the theory. Moreover, giant GH spatial shifts have been observed [10] with a three-layer system in the Kretschmann-Raether configuration at the metal-air interface when the surface plasmon resonance of the metal is excited. Finally, the detection of both GH and IF spatial shifts has been reported [11] for a light beam on a three-layer system totally reflected on the external interface of a dielectric thin film deposited on a high-index substrate.Motivated by these experimental achievements in this paper we analyze theoretically the effect of a surface plasmon resonance not only on GH and IF spatial shifts but also on GH and IF angular shifts. In particular, we investigate the three-layer system glass-gold-air in the Kretschmann-Raether configuration [12,13]. To calculate spatial and angular shifts we use the recently established theory [14], which shows that both spatial and angular GH and IF shifts can be derived in terms of the complex reflection coefficient. We consider the three-layer system glass-gold-air. This is the familiar Kretschmann-Raether configuration [12]: the light beam comes from the prism of glass and reflects with incident angle θ at the interface with air, where there is a thin film of gold with thickness d. In our anaysis the prism of glass has relative permittivity ǫ 0 = 2.19; the thin film of gold has complex relative permittivity: ǫ 1 = −29.02 + 2.03i for a wavelength λ = 830 nm [9]; the air has relative permittivity ǫ 2 = 1.The s-wave and p-wave reflection coefficients r s and r p of this three-layer system can be written in terms of generalized Fresnell equations [12] r s = r 01 s + r 12 s e 2iδ 1 + r 01 s r 12 s e 2iδ ,whereare the reflection coefficient at the 01 and 12 interfaces, andare the z components of the wavevectors of the light. Notice that k z1 gives the ratio between the complex phase parameter δ which appears in Eqs. (1) and (2) and the thickness d of the gold film.It is important to stress that, in general, both s-wave and p-wave ...

“…The maximum shift observed in Ref. [26] was 66 µm or 125 wavelengths of incident light, that is, at least two times larger than the effect observed for surface plasmons [36,40]. Later, in higher-quality photonic crystal systems, even larger values of the Goos-Hänchen shift were obtained [41].…”

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.

“…BSW-based gas, protein, antibody, glucose, and protease detectors as well as BSW-induced enhanced Raman scattering have been successfully demonstrated [6][7][8][9][10][11][12][13]. Different effects in the presence of BSWs have been experimentally observed including the enhancement of fluorescence [14] and magneto-optical effects [15], giant Goos-Hänchen effect [16], and BSW-induced radiation forces [17,18].…”

Abstract:We applied femtosecond laser polymerisation technique to fabricate a novel Bloch surface wave integrated photonic device with a compact coupling scheme. The device consisted of a waveguide, coupling and decoupling gratings and focusing and defocusing triangles. We manufactured an array of devices with varying geometrical parameters of waveguide. Excitation and propagation of Bloch surface wave waveguide modes were studied by direct and back focal plane imaging. The obtained results prove that the maskless and flexible femtosecond laser polymerisation technique may be applied for fabrication of Bloch-surface-wave based integrated photonics.
