- 摘要:we theoretically and experimentally report a newly-designed biosensor, which consists of a particular graphene-oxide (GO)-coated-U-bent long-period fiber grating inscribed in a two-mode fiber (LPFG-TMF). Due to the enhancement of evanescent field, the bent LPFG-TMF is more sensitive to the surrounding refractive index and it allows an extremely high sensitivity. The impact of bent radius on the sensing performance is discussed. The experimental result demonstrates, the sensitivity increases nonlinearly with the surrounding refractive index and the highest sensitivity reaches 6632.32 nm/RIU in
