  Spectral manifestations of hybrid Tamm-microcavity modes in a 1D photonic
crystal bounded with a silver layer and containing a nematic liquid crystal
layer working as a microcavity have been studied using numerical simulation. It
is demonstrated that the hybrid modes can be effectively tuned owing to the
high sensitivity of the liquid crystal to the temperature and external electric
field variations. It is established that the effect of temperature on the
transmission spectrum of the investigated structure is most pronounced at the
point of the phase transition of the liquid crystal to the isotropic state,
where the refractive index jump is observed.
