Fibre Bragg grating photowriting in microstructured optical fibres for refractive index measurement

Tilted Fiber Bragg Grating photowritten in microstructured optical fiber for improved refractive index measurement.

We report what we believe to be the first Tilted short-period Fiber Bragg Grating photowritten in a microstructured optical fiber for refractive index measurement. We investigate the spectral sensitivity of Tilted Fiber Bragg Grating to refractive index liquid inserted into the holes of a multimode microstructured fiber. We measure the wavelength shift of the first four modes experimentally obs...

Fibre Bragg Grating Filters for Optical Communications

Several steps in the development of Fibre optic Bragg grating for application in tuneable wavelength devices intended to DWDM are presented.

Refractive Index Measurement of Liquids Based on Microstructured Optical Fibers

This review is focused on microstructured optical fiber sensors developed in recent years for liquid RI sensing. The review is divided into three parts: the first section introduces a general view of the most relevant refractometric sensors that have been reported over the last thirty years. Section 2 discusses several microstructured optical fiber designs, namely, suspended-core fiber, photoni...

870nm Bragg grating in single mode TOPAS microstructured polymer optical fibre [7753-166]

We report the fabrication and characterization of a fiber Bragg grating (FBG) with 870 nm resonance wavelength in a single-mode TOPAS microstructured polymer optical fiber (mPOF). The grating has been UV-written with the phasemask technique using a 325 nm HeCd laser. The static tensile strain sensitivity has been measured as 0.64 pm/μstrain, and the temperature sensitivity was -60 pm/C. This is...
