Here, we demonstrate a non-destructive quantitative phase imaging method, in conjunction with tomographic reconstruction techniques, to reconstruct the three-dimensional refractive index distribution of a fiber Bragg grating. In addition to being abl

A systematic study was performed on the temperature-dependent fluorescence of (Ba,Sr)2SiO4:Eu2+. The barycenter and extended intensity ratio techniques were proposed to characterize the broadband fluorescence spectra. These techniques and other known

A scheme that provides an alternative mechanism for temperature sensing via a fluorescence intensity ratio (FIR) is proposed. The rate of energy transfer between rare-earth ions in a crystal or glass host is temperature dependent, and as such exhibit

A numerical investigation on how fiber Bragg grating fabrication conditions using the phase mask technique affect the harmonic components of the Bragg wavelength is presented. Both the properties of the phase mask and saturation effects are investiga

Fiber Bragg gratings written using a phase-mask exhibit a complex refractive index pattern in the fiber core, as observed in differential interference contrast (DIC) microscopy. This results in dual periodicities along the fiber core and gratings at

Effects of fabrication conditions on an alternative type of pi-phase-shifted fibre Bragg grating at twice the Bragg wavelength were investigated, showing that slight variations in the alignment of phase mask affect the grating spectra.

Optical fibre Bragg gratings were fabricated in 3 different fibres, and their spectra at 3 harmonics were measured and cross-compared with images of their internal complex refractive index profiles obtained via differential interface contrast imaging

The effect of bending on the twin peaks of an alternative type of pi-phase shifted fibre Bragg grating (FBG) (embedded in a resin) at twice the Bragg wavelength, has been investigated. Variation of the direction of bending resulted in corresponding c
