High Resolution NIR TFBG-Assisted Biochemical Sensors [PDF]
Journal of Lightwave Technology, 2015 Tilted fiber Bragg gratings (TFBGs) have shown to be a suitable tool for exciting surface plasmon waves in a comparable manner as in typical attenuated total reflection Kretschmann configurations. In this paper, we present a comparative analysis of the characteristics of prism and grating configurations for generating surface plasmon resonance (SPR ...

Twist Sensor Based on Long Period Grating and Tilted Bragg Grating Written in Few-Mode Fibers
IEEE Photonics Journal, 2018 A twist sensor based on a few-mode long period grating (LPG) and a tilted fiber Bragg grating (TFBG) is proposed and demonstrated. The LPG, inscribed in a step index few-mode fiber by a CO2 laser, is utilized to excite the LP11 core mode.
