Generation of infrared surface plasmon resonances with high refractive index sensitivity utilizing tilted fiber Bragg gratings.
We demonstrate the use of tilted fiber gratings to assist the generation of localized infrared surface plasmons with short propagation lengths and a sensitivity of dlambda/dn = 3,365 nm in the aqueous index regime. It was also found that the resonances could be spectrally tuned over 1,000 nm at the same spatial region with high coupling efficiency (in excess of 25 dB) by altering the polarizati...
متن کاملFabrication and Characterization of the Fiber Optical Taper for a Surface Plasmon Resonance Sensor
For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...
متن کاملLight Polarization-Assisted Sensing with Tilted Fiber Bragg Gratings
Tilted fiber Bragg gratings (TFBGs) are short-period gratings for which the refractive index modulation of the fiber core is angled by a few degrees with respect to the perpendicular to the propagation axis. They induce two kinds of light coupling: the self-backward coupling of the core mode at the Bragg wavelength and the backward coupling between the core mode and several tens of cladding mod...
متن کاملCompact Optical Fiber 3D Shape Sensor Based on a Pair of Orthogonal Tilted Fiber Bragg Gratings
In this work, a compact fiber-optic 3D shape sensor consisting of two serially connected 2° tilted fiber Bragg gratings (TFBGs) is proposed, where the orientations of the grating planes of the two TFBGs are orthogonal. The measurement of the reflective transmission spectrum from the pair of TFBGs was implemented by Fresnel reflection of the cleaved fiber end. The two groups of cladding mode res...
متن کاملFiber Bragg Grating Sensors and Sensor Arrays
Fiber Bragg gratings have found widespread application in sensor systems, e. g. for temperature, strain or refractive index measurements. The concept of fiber Bragg gratings allows also in a simple way the realisation of arrays of such sensors. The development of such optical fiber sensor systems often requires special fibers and grating structures which may go beyond more conventional Bragg gr...
