Supercontinuum Generation in Tapered Fibers
Asia Communications and Photonics Conference and Exhibition, 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 1.25 μm 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 photonic crystal fibers
SPIE Proceedings, 2006Tapered photonic crystal fibers (PCFs), similar to tapered conventional fibers, can be either adiabatic of nonadiabatic. Here, we examine the adiabaticity of the PCF taper and obtain three-dimensional plots showing the evolution of power flow inside the tapered PCF. Also, we analyze different taper shapes, such as the linear taper, raised-cosine taper,

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 ...

Dispersion characterization of tapered fibers
SPIE Proceedings, 2004The dispersion curves of tapered fibers at various geometries are characterized by using white-light interferometry. In this presentation, the white-light interference patterns at frequencies near the taper’s second zero-dispersion frequency are measured and discussed in detail.

IEEE Photonics Technology Letters, 2006
We present several simple sensitive fiber-optics-based sensors that utilize a biconical fiber taper. A displacement sensor with 100-nm accuracy, a temperature monitor with sensitivity DeltaT~1degC, and a refractive-index sensor capable of measuring Deltan~1.42times10-5 are demonstrated using tapers made from a standard single-mode ...

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 ...
