A half-filling technique was demonstrated to improve the bending properties of a fluid-filled photonic crystal fiber. Such a technique can realize to fill selectively a fluid into half of air holes in a PCF. The bending properties of the half-filled PCF are quite different from those of the fully-filled PCF. Distinct bending properties were observed when the half-filled PCF was bent toward diff...

Tisato Kajiyama Faculty of Engineering, Kyushu University, Fligashi-ku, Fukuoka 812 A bimolecular membrane of phospholipids such as lecithin is in a state of liquid crystal capable of reversible structural modifications and its permeation property depends on such reversible change. Artificial amphiphiles with monoalkyl and dialkyl groups form multilamellar liposome composed of the bimolecular l...

The anisotropic superconducting properties of PbTaSe2 single crystal is reported. Superconductivity with T c  =  3.83  ±  0.02 K has been characterized fully with electrical resistivity ρ(T), magnetic susceptibility χ(T), and specific heat C p (T) measurements using single crystal samples. The superconductivity is type-II with lower critical field H c1 and upper critical field H c2 of 65 and 45...

Searching for new nonlinear optical (NLO) crystals to be used in the infrared (IR) region is still a challenge. This paper presents the synthesis, crystal structure and properties of a new halide, RbHgI3. Its non-centrosymmetric single crystal can be grown in solution. In its crystal structure, all the polar [HgI4] groups align in such a way that brings a favorable net polarization. The measure...

This paper presents a triangular-lattice photonic crystal fiber for analysis of nearly zero ultra-flattened dispersion like 0.96 -0.86 ps/nm/km with very low confinement loss less than 10 db/km, moderate effective area, lower splice loss & nonlinear coefficient property of photonic crystal fibers. A five-ringed photonic crystal fiber have be designed using Comsol 4.2 with the finite element met...

Nonlinear optical crystal of L-methioninium nitrate was grown by slow evaporation method from aqueous solution at room temperature. The lattice parameters and crystal structure of the grown crystal were identified and confirmed using single crystal X-ray diffraction analysis. Fourier transform infrared spectroscopy analysis was made to study the vibrational functional groups present in the crys...
