Fig 7. The wavelength shift versus the surrounding RI for fixed
diameter.
Figure 8 (A-C) displays the spectral shifts of the proposed RI fiber
sensor with CLF diameter of 50 μm and varies lengths against various RI
values. These results confirm that the RI sensitivity is improved by
decreasing the diameter of the CLF. The calculated sensitivities were
arranged in table 7, 8 and 9 for length of 20, 25 and 30 mm
respectively.
