▎ 摘  要

NOVELTY - The sensor has a broadband light source (1) for producing incident light. A polarization controller (2) receives non-polarized light output by the broadband light source. A sample pool (5) is placed with a first graphene integrated slant fiber grating (4) that is coated with graphene. A second graphene integrated slant fiber grating is formed after inputting polarized light into the graphene. A spectrum analyzer (6) monitors output spectral changes of the first graphene integrated slant fiber grating. A single-mode optical fiber (3) is connected with the polarization controller and the first graphene integrated slant fiber grating. The first graphene integrated slant fiber grating is connected with the spectrum analyzer. USE - Graphene integrated inclined fiber Bragg grating refractive index sensor. ADVANTAGE - The sensor has high sensitivity, and realizes wide wave band dynamic control and quick response, and changes mode characteristics and resonant wavelength of the fiber grating to control and optimize sensing performance of a graphene integrated tilt fiber grating sensor unit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene integrated inclined fiber bragg grating refractive index sensitivity controlling method. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a graphene integrated inclined fiber bragg grating refractive index sensor.
