Optical Fiber Gratings Immunoassays [PDF]

open access: yesSensors, 2019
Optical fibers are of growing interest for biosensing, especially for point-of-care and biomedical assays. Their intrinsic properties bestow them sought-after assets for the detection of low concentrations of analytes. Tilted fiber Bragg gratings (TFBGs)

Point-by-point inscription of chirped apodized fiber Bragg gratings for application as ultrashort pulse stretchers

open access: yesResults in Physics, 2022
There are special requirements for chirped fiber Bragg gratings used as stretchers in ultrafast fiber lasers. The benefits of fabricating fiber stretchers by the femtosecond point-by-point single-shot technique are described.

In-fiber single-polarization diffraction grating based on radiant tilted fiber grating [PDF]

open access: yesOptics Letters, 2019
In this Letter, we propose an in-fiber single-polarization diffraction grating based on a radiant tilted fiber grating (TFG), in which the s-polarization light could be diffracted from the fiber core to free space with the wavelength-dependent diffraction angle.

Interrogation unit for fiber Bragg grating sensors that uses a slanted fiber grating [PDF]

open access: yesOptics Letters, 2004
A novel interrogation technique for fiber Bragg gratings is presented. It is based on measuring the characteristics of the outgoing near-field radiation from a tilted fiber grating. This scheme was experimentally checked and was found to offer a wide wavelength interrogation range as well as a good linearity, stability, and wavelength resolution.
