Surface plasmon polariton excitation was demonstrated by fluorescent light from organic para-hexaphenylene (p-6P) nanofibers grown directly on a silver thin film surface. We show results of both photoluminescence lifetime measurements and angle-resol

An interference of two beams coming from one laser is a well-known and popular experiment. But is it possible to obtain interference fringes using two completely independent laser sources? If the answer is ‘yes’, is such an observation available

Near-field characterization of surface plasmon polaritons on a nanofabricated transmission structure
The tailoring of plasmonic near fields is central to the field of nanophotonics. Detailed knowledge of the field distribution is crucial for design and fabrication of plasmonic sensors, detectors, photovoltaics, plasmon-based circuits, nanomanipulato

We investigate experimentally a Bose Einstein condensate placed in a 1D optical lattice whose phase or amplitude is modulated in a frequency range resonant with the first bands of the band structure. More precisely, we study the effect of the strengt

We report on a new method to calibrate the depth of an optical lattice. It consists in triggering the intrasite dipole mode of the cloud by a sudden phase shift. The corresponding oscillatory motion is directly related to the intraband frequencies on

We report on an optical mirror for cold rubidium atoms based on a repulsive dipole potential created by means of a modified recordable digital versatile disc. Using the mirror, we have determined the absolute value of the surface plasmon polariton (S

An experimental setup allowing the observation of two-laser interference by the naked eye is described. The key concept is the use of an electronic phase lock between two external cavity diode lasers. The experiment is suitable both for undergraduate

We applied optogalvanic spectroscopy to observe Zeeman effect in the evanescent wave in Ar gas with the help of a single-mode diode laser. The use of an homogenous external magnetic field enabled us to observe different π and σ Zeeman split lines c

The two-photon fluorescence spectroscopy in the vicinity of the surface has been performed for Cesium atoms. One of the laser beams was directed perpendicularly to the surface, whereas the second one excited an evanescent wave propagating along the s
