Polarization Effects in Tilted Fiber Bragg Grating Refractometers
Journal of Lightwave Technology, 2010The polarization effects in tilted fiber Bragg grating (TFBG) refractometers are investigated theoretically. The polarization effects may degrade the sensor performance greatly, and should be considered to achieve high-precision surrounding refractive index (SRI) measurement.

Shaping the radiation field of tilted fiber Bragg gratings
Journal of the Optical Society of America B, 2005Over the past several years polarization-sensitive mode-coupling characteristics of tilted fiber Bragg gratings have been exploited for the development of a number of useful devices, including fiber polarimeters, gain flattening filters, spectrum analyzers, and polarization-dependent-loss compensators. Although a variety of tools are available to model

Temperature-insensitive fiber Bragg grating tilt sensor
SPIE Proceedings, 2010A novel fiber Bragg grating (FBG) tilt sensor is proposed to detect the magnitude as well as the direction of a twodimensional inclination by using four FBGs. High angle sensitivity and measurement resolution has been achieved and the temperature effect has been eliminated completely without additional temperature compensation schemes.

Enzymatic tilted fiber Bragg grating for glucose biosensing
26th International Conference on Optical Fiber Sensors, 2018We proposed and experimentally demonstrated a label-free biosensor based on enzyme-immobilized tilted fiber Bragg grating (TFBG) for low concentration glucose detection by using the fine spectrum structure of the TFBG.

We experimentally demonstrated a tilted fibre Bragg grating (FBG) demodulator that has a simple and compact scheme. Using this, wavelength-encoded information from a dual head strain sensor is demodulated with high stability and accuracy, independent of temperature perturbation at both sensor and demodulator FBG.

Femtosecond laser direct writing tilted fiber Bragg gratings in multicore fiber
Optics LettersIn this Letter, we propose a new method utilizing femtosecond laser direct writing technology to rapidly inscribe high-quality tilted fiber Bragg gratings (TFBGs) in multicore fibers (MCFs). A series of TFBGs with varying tilt angles were directly inscribed in MCFs using the Plane-by-Plane (Pl-by-Pl) method, and the writing time for a 4 mm long TFBG ...
