Schematic diagram of the MOF Bragg grating as a microfluidic sensor.
SEM images [(a) and (b)] and side-view microscopic image (c) of the fabricated MOF, and its modeling shape and dimension for numerical simulation (d).
The reflection spectrum of the fabricated MOF Bragg grating. The insets show the calculated mode patterns of corresponding reflection peaks.
Comparison of the measured and simulated RI dependences of the Bragg wavelengths of the fundamental mode of the MOFBG. The inset shows the simulated dependences of the first three modes.
Comparison of the temperature responses of the first two-order modes of the MOFBG [(a) and (b)] and the fundamental mode of a conventional FBG (c).
