Abstract

Temperature tunability of a polariton mode is reported for the first time. Using spontaneous, as well as stimulated near-forward Raman scattering experiments, we have observed the shift of the polariton dispersion curve associated with the 200 cm^-1 ferroelectric mode in LiTaO₃ towards lower frequencies, as temperature is raised from room temperature to 306°C. This behavior can be quantitatively explained through the classical-oscillator dispersion theory.
