Photonic bandgap fiber tapers and in-fiber interferometric sensors
Optics Letters, 2009Nonadiabatic tapers in hollow-core air-silica photonic bandgap fibers (PBFs) were fabricated by the use of a fiber fusion splicer. In addition to the well-known scaling down of fiber dimensions, the innermost rings of air holes were found collapsed or significantly deformed, which results in almost doubling the diameter of the hollow core in the ...

Optics Letters, 2016
Employing finite difference time domain simulations, we demonstrate that electromagnetic field enhancement is substantially greater for tapered optical fibers with plasmonic nanostructures present on their tips as compared with non-tapered optical fibers having those plasmonic nanostructures, or with tapered optical fibers without the plasmonic ...

Supercontinuum generation in tapered fibers
SPIE Proceedings, 2009Here we demonstrate a supercontiuum spectrum generated in a tapered fiber pumped by a Ti sapphire laser with 130fs pulse width at 800nm centre wavelength. The tapered fiber with the diameter of 1.25µm and the length of 16cm was made by using a tapered machine. The supercontiuum range is from 500nm to 900nm.

Tapered enlarged ends in multimode optical fibers
Applied Optics, 1982Radiation characteristics of multimode fibers with enlarged tapers were investigated on a number of samples obtained by varying the fiber drawing speed with a given law corresponding to a prefixed taper profile. The characterization of the fibers was made by near- and far-field intensity pattern measurements as well as by measuring the losses ...

Manipulation of tapered optical fibers
2009 III Conference of University of Guanajuato IEEE Students Chapter (IEEExPO), 2009Tapered optical fibers are difficult to handle when they have a diameter below 15 micrometers. Given the fragility of tapered region, an automatic mechanism to handle will assure that the optical fiber will not be broken because of shearing stress induced by manipulating if manually.

Tapered fiber tips for fiber optic biosensors
Optical Engineering, 1995Tapered fiber tips with different geometries are fabricated for developing a fiber optic biosensor. Fluorescence experiments are performed to compare the coupling efficiency of light for different fiber tip configurations. When light is generated in a "thick" layer (> 1 μm) around a fiber core, the continuously tapered tip with the steepest taper ...

Tapered Fibers for Cell Studies
2007Optical fiber sensors are extensively used in monitoring physical, chemical and biochemical conditions (Mignanai and Baldini, 1995; Pilevar et al., 1998; Cullum et al., 2000). Specifically, these sensors have found a niche in the field of biosensors for the detection and classification of various tissue properties such as cell growth and decay, and ...
