Singlemode propagation into depressed-core-index photonic-bandgap fibre designed for zero-dispersion propagation at short wavelengths
TL;DR: In this article, a depressed core-index photonic bandgap fiber with a cladding made of alternate high and low index layers is presented, which exhibits zero chromatic dispersion shifted towards wavelengths as short as 1 /spl mu/m.

Evaporation of volatile compounds in suspended-core fibers
TL;DR: Strong differences between the evaporation processes of acetone and isopropyl alcohol were observed, both in terms of the signal's intensity fluctuations and total duration.
Strain and Temperature Discrimination Using Modal Interferometry in Bragg Fibers
TL;DR: In this paper, the strain and temperature sensing characteristics of a modal interferometer based on two Bragg fibers have been investigated, and it appears that the sensitivity to the sensing parameters are different for the two BRagg fibers, which makes it possible to fabricate several sensing configurations based on the combination of these two bragg fibers.
12 nm FWHM 20 dB stop-band filter based on cascaded dual concentric core fibre filters
TL;DR: A spectral stop-band filter with peak attenuation = 5 dB, full width at half-maximum (FWHM) = 31 nm based on a dual asymmetric concentric core optical fibre is investigated and an efficient 12 nm FWHM 20 dBpeak attenuation is demonstrated by cascading four filters.

TL;DR: In this paper, a preliminary study of the behavior of two different interferometric fiber optic sensors and two different wavelength selective fiber optic sensor is performed, and a comparison of their sensitivities and resolutions is carried out to analyze their performance as sensors for cryogenic temperatures.
