abstract = "We investigate the effect of fabrication parameters (nonequal
surface current densities, impurities inside the structure, etc.)
and loss factor on reflectivity and transmittivity measurements
from porous silicon Fabry-P{\'e}rot cavities with finite-size
substrate thicknesses. We apply the formalism based on wave
cascade matrix method for obtaining dependencies of reflectivity
and transmittivity. From our analysis, we note the following
results. First, resonance behavior of reflectivity and
transmittivity changes only when optical/physical properties of
middle layers of the cavity alter. Second, for lossless cavities,
while reflectivity and transmittivity considerably change with
surface characteristics (optical/physical properties of first
layers), transmittivity is significantly modified by a change of
optical/physical properties of middle layers (microcavity region).
Third, loss inside a FP cavity makes the transmittivity more
immune to variations in optical/physical properties of middle
layers. Finally and most importantly, transmittivity values at
resonance wavelength as well as the resonance wavelength shift can
be utilized for the identification of unknown chemical/biological
molecules by lossless FP cavities. For validation of these
results, we carried out reflectivity and transmittivity
measurements from some arbitrarily chosen positions but around the
center of two fabricated FP cavities resonating at 1456 nm and at
542 nm.",
