“…At the same time, photonic crystals can be entirely made of transparent materials and devoid of heating problems. The force action of the BSW field in photonic crystals on micro-objects is considered in [74][75][76]. It is shown that this effect can be used for optical control.…”

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.

“…Improvements in optics have been incremental and based on the classical theory of refraction and improved materials and manufacturing. The static situation is rapidly changing with the discovery of photonic band gaps (PBG) [15–16], surface-bound states on dielectrics or metallic structures [17–19] and the application of classical electrodynamics (Maxwell’s equations) to nanoscale structures [20–21], all of which are providing new methods to manipulate the flow of optical energy using nano-scale structures.…”

Fluorescent samples typically emit isotropically in all directions. As a result large lenses and other optical components are needed to capture a significant fraction of the emission, and complex confocal microscopes are required for high resolution focal-plane imaging. Complex optical systems are necessary for manipulation of light propagating in free-space. All propagating light is affected to some extent by surfaces, obstacles or apertures resulting in diffraction. Even the most highly collimated laser beams expand with distance from the source. This expansion is described by Rayleigh range ZR = πω20/λ0, where ω0 is the most narrow beam waist size and λ0 as the free-space wavelength. The value of ZR is the distance over which a Gaussian beam increases its cross-sectional area by a factor of two. The importance of diffraction can be understood by considering a 500 nm plane wave incident on an opaque mask with a 2 micron diameter hole. Even for this seemingly favorable case, with ω0 4-fold larger than the wavelength, ZR = 25 microns, showing that light passing through the 2 micron aperture is diffracted and quickly diverges with distance, and the beam area expands 2-fold in 50 λ0. Bessel beams have remarkable property of being able to travel long distances, over 1000 times the wavelength, without diverging into a wider beams. The diameter of the beam can be diffraction limited over the entire distance. To be specific, a 2 micron diameter beam retains a 2 micron diameter for long distance, and a point source results in a Bessel beam with a diameter comparable to the diffraction-limited resolution of the optics. In all previous reports the Bessel beams were formed by an incident light source, typically with plane-wave illumination on a circular aperture. It was not known if Bessel beams could form using an incoherent fluorescent light source, especially within near-field distances from surface where plane waves have not yet formed. Herein we demonstrate transformation of the emission from fluorescent polystyrene spheres into non-diverging beams which propagate up to 130 mm (13 cm) along the optical axis with a constant diameter. This is accomplished using a planar metal film, with no nanoscale features in the X–Y plane, using surface plasmon-coupled emission. Furthermore, using samples which contain many fluorescent polystyrene spheres in the field-of-view, we demonstrate that an independent Bessel beam can be generated from any location on the metal film. The extremely long non-diffracted propagation distances offer new opportunities in fluorescence sensing and imaging.
