Abstract
As of late, the various techniques
from the materials science and biophysics
are utilized to study the physical
properties of the microstructure
of the chemical and biological specimen.
Through a considerable many
of them give phenomenal sensibility,
they have a few requirements concerning
electromagnetic interference, fabrication
complexity and specific laboratory
conditions for operating. Hence,
to overcome these constraints the new
family of micro-scale fiber optical sensors
was introduced. There are several
methods to fabricate microfibers with
different microtechbology. However,
the techniques with more simple, economical
and robust fabrication process
are still developing. Therefore, this
study proposes the fabrication process
of widely interested tapered fiber optic
microsensor via Laser Splicing System
and characterization of produced tapered
microfibers in terms of external
RI sensitivity. The final product that
was achieved is the fiber with the least
waist diameter 19 mm has RI sensitivity
of 156.8215 nm/RIU and agreeable
linear correlation between the wavelength
shift and RI change. In addition,
the detailed fabrication process
with characterization method is presented
in the following sections. Moreover,
the observed trends in fabrication
process and recommendations based
on the practice experience are also suggested
in this report.
