Abstract
The essay theoretically analyses the Fermi distribution of gradient
refractive index waveguide cladding mode absorption spectrum
characteristics, it also analyses the structure of the sensitivity within
cladding absorption associated with the waveguide parameters, test
sensitivity is associated with the waveguide mode and the waveguide
parameters, especially with the waveguide layer thickness which is very
sensitive to correlation. The analysis of results was confirmed by the
Experiment of Guided Wave Loss Test. In the experiment the interaction ratio
is measured, with waveguide in corresponding thickness and the mode in
maximal interaction ratio is used as a sensing device which is used as a
waveguide circuit with double-sample serial structure for measuring the
liquid-clad absorption loss. The results show a very significant linear
relationship between solution concentration and refractive index's imaginary
part which characterizes the solution cladding absorption feature. By using
this sensing relationship, the concentrations C. I. Pigment Green7 solution
samples 13 with kinds of different concentrations have been measured. The
standard deviation between the measured values and the actual values is less
than 0.07%.
