abstract = "We propose a novel method for identification of various gases
using combined measurements of wavelength shift (\Δ
\λ0) and reflectivity difference (\Δ R). The method
relies on plotting the measurement data on the\Δ R-\Δ
\λ0 space and exploits in the identification process the
effect of significant loss behavior of bulk silicon near or within
the visible range (for lossless gas vapors). It has been validated
by reflectivity measurements on a Fabry-P{\'e}rot cavity
resonating around 745 nm for four different gas vapors whose
reflective indices are close to each other and by two metrics for
separability/identification analysis by the scattering matrix
method. It is noted that the combined measurements of\Δ
\λ0 and\Δ R result in better identification than that
obtained by the measurement of\Δ \λ0 (or\Δ R)
itself.",
