Study on the SRI Sensing Characteristics of PFBG and TFBG

2013
The sensing characteristics of surrounding refractive index (SRI) were investigated on the pretreated FBG (PFBG) by hydrofluoric acid (HF) etching treatment and the tilted fiber Bragg grating (TFBG) with an angle of 4° through several experiments, in which the SRI ranges from 1.40 to 1.45. The results demonstrated that the SRI sensing characteristic of

Refractive index and temperature sensor based on TFBGs in multicore fiber

26th International Conference on Optical Fiber Sensors, 2018
We selectively inscribe 2o and 7o Tilted Fiber Bragg Gratings (TFBGs) in a seven-core fiber. We use the crosstalk between cores induced by the TFBGs for temperature and refractive index sensing. We have demonstrated that the higher the tilted angle the more sensitive sensor.

Analysis of time-controlled electroless deposited gold films on TFBGs

2016 Photonics North (PN), 2016
Electroless deposition of gold was used to coat optical fibers with a TFBG inscribed, to analyze the performance of films with different thickness when measuring changes in the refractive index of an external medium.

Hybrid Polarizing Grating and TFBG based SPR Refractive Index Sensor

2019 18th International Conference on Optical Communications and Networks (ICOCN), 2019
In this paper, we report a Surface Plasmon Resonance (SPR) Surrounding Refractive Index (SRI) sensing system based on a hybrid grating structure comprising of a 45o tilted fiber grating (TFG) and a silver coated small angle tilted fiber Bragg grating (TFBG) that have been inscribed into a single mode fiber in series.
