Analysis of optical properties of fundamental-mode in waveguide tapered fibers

An analysis of optical properties of fundamental-mode in waveguide tapered fibers is theoretically investigated and realized in this paper. The waveguide device is tapering an SMF-28 fiber to few tens of micrometers of diameter. For discussing the cladding size of waveguide structure affects the fundamental-mode cutoff (FMC) and the optical characteristics of the devices, to etch outer cladding...

Adiabatically tapered periodic segmentation of channel waveguides for mode-size transformation and fundamental mode excitation.

We report modeling, fabrication, and characterization of tapered waveguides, using periodically segmented annealed proton exchange in LiNbO(3). For a taper transforming the 1/e full width (intensity) mode size from 6.0 microm x 4.4 microm to 2.0 microm x 1.3 microm, 0.4-dB excess loss was observed. The large, slightly elliptical mode can ease coupling to single-mode fibers and circular free-spa...

Soliton propagation and polarization mode-locking in birefringent optical fibres

In recent years much work has been devoted to the development of erbium-doped fibre lasers [ 1-91. because a broad zain bandwidth centred nearly I.54 urn. cegative group velocitv dispersion and tight confinement of optical field allow the exploitation of nonlinear optical effects for very efficient generatlon of ultra-short optical pulses. In the last few years several schemes of fibre soliton ...

On-chip optical mode exchange using tapered directional coupler

We present an on-chip optical mode exchange between two multiplexed modes by using tapered directional couplers on silicon-on-insulator platform. The device consisting of mode multiplexing and mode exchange is compact with relatively large fabrication error tolerance. The simulation results show efficient higher order mode excitation and mode exchange. A low excess loss less than 0.5 dB and hig...

Novel Highly Sensitive Protein Sensors Based on Tapered Optical Fibres Modified with Au-Based Nanocoatings

Novel protein sensors based on tapered optical fibres modified with Au coatings deposited using two different procedures are proposed. Au-based coatings are deposited onto a nonadiabatic tapered optical fibre using (i) a novel facile method composed of layer-by-layer deposition consisting of polycation (poly(allylamine hydrochloride), PAH) and negatively charged SiO 2 nanoparticles (NPs) follow...
