The broadening of the oxygen absorption line P9P9 due to wall collisions of entrapped oxygen gas in nanoporous solid discs of average pore diameters between 70 and 150 nm is studied using GAs in Scattering Media Absorption Spectroscopy (GASMAS) method. A model based on the kinetic theory of gasses is used to find a correlation between the wall-coll...

We demonstrate a fiber in-line single photon source based on a hybrid system of colloidal single quantum dots deposited on an optical nanofiber and cooled down to cryogenic temperature (3.7 K). We show that a charged state (trion) of the single quantum dot exhibits a photo-stable emission of single photons with high quantum efficiency, narrow linew...

We present new high-resolution absorption data for the important sesquioxide laser material Yb:Lu2O3 for the spectral range of 880–1020 nm, at various temperatures between 8 and 300 K, and for the zero-phonon region from 960 to 990 nm, at temperatures from 8 to 300 K. We have experimentally observed the C3i (0,1)–(1,3) transition for the first time...

Spiral phase plate is the most commonly used optical element for generating an optical vortex beam. It is widely applied due to its higher efficiency and less complex structure compared to other optical elements used for this purpose. The paper presents a simple, reliable and high-performance technology for manufacturing of a spiral phase plate on ...

The work present investigates the dependence of the coherence time of an individual spectral supercontinuum on the intensity of femtosecond pumping during its generation in the water jet in the absence of filament. The results obtained show that the coherence time decreases along with pump intensity increase. Experimentally and by means of numerica...

Linear photon-number resolution is the key to quantum tomography. However, it is difficult to realize ideal linear photon-number resolution through multi-pixel technology because of the lack of detectors with both an ultrahigh quantum efficiency and infinite pixel number. In this letter, a photon-number-resolving detector approaching linear resolut...

In this paper, two SPR biosensor configurations utilizing Fe2O3 layer coupled with Au thin film in the angular interrogation mode have been proposed and analyzed theoretically. The proposed configurations are prism—Au–Fe2O3–Au—sensing medium and prism—Fe2O3–Au–Fe2O3—sensing medium. The reflectivity was calculated as a function of incident angle bas...

In this paper, a new process to deal with measurement error is proposed using smoothing, regression, and model selection. The main objectives of this research are to construct a theoretically reliable process to deal with the measurement errors and to validate the process with a case study for refractive index estimation of water. The proposed proc...

We theoretically propose a novel liquid filled suspended core photonic crystal fiber as a new class of microstructure optical fiber for ultrabroad supercontinuum generation. We emphasize the advantage of liquid infiltration in enhancing the fiber nonlinearity. To further enhance the nonlinearity of the liquid-infiltrated fibers, we introduce a susp...

We established an experimental normalized dataset containing 340 images of interference patterns for several different polymeric fibres using a two-beam polarizing interference microscope. This dataset includes the three main classes for the deformation in fibres (normal stretching, necking and crazing phenomena). To our knowledge, this is first ex...
