Principle and demonstration of operando monitoring thermal effects via a gold-coated TFBG optical fiber sensor.

Caption

a, Schematic illustration of a CNTs/Au-FOS with a TFBG in the fiber core and an Au mirror (4 µm) at the end of fiber. The insets are the simulation of guided mode field intensity distributions for cladding mode and core mode. b, Reflection spectrum of the fiber sensor in water, and the corresponding wavelength of high-order cladding (HC) modes for HC (90-108) and low-order cladding (LC) mode for LC (39-61), and core. c, Wavelength shifts (∆λ) and corresponding spectral responses (the insets: HC (99), LC (49) and core) due to photo-induced catalytic processes over the Au film.
