Tilted fiber bragg gratings for label-free biosensing

open access: yesLEOS 2008 - 21st Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2008
We present fibre-optic-based biosensors for the specific detection of biological species. Three methods for immobilization of biomolecules at the sensor surface have been investigated using Bovine Serum Albumin (BSA) and anti-BSA as model biospecific pair.

Fiber Optic Vibration Sensor Based on the Tilted Fiber Bragg Grating

open access: yesAdvances in Materials Science and Engineering, 2013
A temperature-insensitive fiber optic vibration sensor based on the tilted fiber Bragg grating (TFBG) is presented. The sensing head is formed by insertion of a small section of MMF between a single-mode fiber and the TFBG. The reflection light from this

Plasmon resonances in gold-coated tilted fiber Bragg gratings [PDF]

open access: yesOptics Letters, 2007
The transmission spectrum of fiber Bragg gratings with gratings planes tilted at a small angle (2 degrees -10 degrees) relative to the fiber axis shows a large number of narrowband cladding mode resonances within a 100 nm wide spectrum. When a gold coating with a thickness between 10 and 30 nm is deposited on the fiber, the transmission spectrum shows ...

Gasoline Quality Sensor Based on Tilted Fiber Bragg Gratings

open access: yesPhotonics, 2019
We report on the study of an intensity-based optical fiber sensor for gasoline quality monitoring. The sensor setup employs two Bragg gratings with different spectral responses to interrogate the optical response of a tilted Bragg grating.

Experimental determination of the characteristics of a transmission spectrum of tilted fiber Bragg gratings [PDF]

open access: yesMetrology and Measurement Systems, 2019
In this article, we study tilted fiber Bragg gratings (TFBGs) with tilt angles of 6◦ and 8◦, their transmission spectra, and spectral parameters that have a linear dependence on the refractive index of the environment.

Plasmonic sensors based on tilted Bragg gratings in multicore optical fibers [PDF]

open access: yesOptics Express, 2021
Bare and gold-coated tilted fiber Bragg gratings (TFBGs) can nowadays be considered as a mature technology for volume and surface refractometric sensing, respectively. As for other technologies, a continuous effort is made towards the production of even more sensitive sensors, thereby enabling a high-resolution screening of the surroundings and the ...
