中文摘要

A novel fiber-optic localized plasma resonance
(FO-LPR) sensor composed of a U-shape optical fiber was
proposed and demonstrated in this study. The U-shape
optical fiber was fabricated by a femtosecond laser micromachining
system. The dimensions of the U-shape zone
were 100 lm in depth measured from the surface of the
polymer jacket layer, 80 lm in width in the jacket layer,
60 lm in width in the cladding layer. The total length is
5 mm. After laser annealing treatment, the average surface
roughness was 205.8 nm as determined by Atom Force
Microscope (AFM). The exposed surface of the U-shape
fiber was modified with self-assembled gold nanoparticles
to produce the FO-LPR sensor. The response of the sensor
shows that the signal increases linearly with increasing
refractive index. The sensor resolution of the sensor was
determined to be 1.06 9 10-3 RIU.
