Intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings

, 2013
An intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings is proposed and experimentally demonstrated. The sensor is formed by a tilted-fiber Bragg grating (TFBG) coated by magnetic fluid (MF) and cascaded by a ...

40 GHz-rate all-optical cross-modulation of core-guided near infrared light in single mode fiber by surface plasmons on gold-coated tilted fiber Bragg gratings

APL Photonics, 2019
All-optical control of Surface Plasmon Polaritons (SPPs) can switch light with high speed and a large signal to noise ratio. We demonstrate 25 ps-time scale switching of continuous wave light by pump pulses copropagating in the same single mode fiber at ...

Four-wave mixing generation in carbon nanotube-coated optical fiber grating

, 2011
Four-wave mixing (FWM) in single-walled carbon nanotubes (SWCNTs) wrapped on the cladding of a tilted fiber Bragg grating (TFBG) is demonstrated. FWM is generated by TFBG induced interaction of the core mode with the SWCNTs outer cladding. The wavelength

Manufacture of Tapered Fibers and FBG Writing

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
This article discusses procedures for production of tapered fibers in different diameters (tapers) and Bragg gratings writing (tFBG) in such fibers. The reflection spectra in different tFBGs are compared with a FBG written in standard single-mode fiber ...
