| Thermal Emission in Nano-scale |
Micro- and Nanooptics Laboratory conducts research and development of subwavelength micro- and nanostructured optical elements that perform a space-variant polarization manipulation accompanied with geometric phase. These devices are used for our experimental research of vectorial singular optics, optical vortex carrying an orbital angular momentum, surface phonon- and plasmon-polaritons exciting on micro-structured surface and in microcavities.

Cover Story The development of a new branch of physics — spin optics — has taken a step forwards thanks to a direct observation of the influence of the spin Hall effect of light on photon trajectories. Konstantin Bliokh and co-workers report two important observations: first, a spin-dependent deflection of photons; and second, precession of the Stokes vector along a coiled ray trajectory. The measurements, which match theoretical predictions, verify the role that the topological monopole and Berry phase play in the evolution of light. The experiments were made by passing a circularly polarized beam of red light from a HeNe laser into a small glass cylinder at a grazing angle using a prism. Once inside the cylinder the beam travels in a helical trajectory along the glass–air interface and is collected and analysed at the far end using polarization optics and a CCD camera. [pdf] |
