A general theory of Raman scattering in piezoelectric slab waveguides is presented. If the anisotropy of the uniaxial waveguide material is sufficiently large, incident slab-guided waves can be scattered by polaritons of the upper branch of the polariton dispersion curve. The angular dependence ω 2...
The theoretical investigation of stimulated Raman scattering (RS) by polaritons under nonstationary conditions, when local or wave nonstationary properties are separately important has been carried out on the basis of a fluctuation-dissipation method. General experssions are found which describe the ...

An experimental investigation was made of Raman light scattering by polaritons as a function of their frequency in lithium iodate and lithium formate crystals. The spectra were recorded and the intensity was measured using an optical multichannel analyzer connected to a minicomputer in an pptical syst...

Soliton 1 excites coherent lattice vibrations (orange) via impulsive simulated Raman scattering. The trailing soliton 2 samples the ultrafast refractive modulation—arising from combined nonlinear electronic and nuclear contributions in the Kerr-lens configuration. b Simulated evolution of single-shot ...
The theory presented in Part I [1] for the Raman scattering efficiency of polaritons in uniaxial piezoelectric crystals is used to interpret experiments on the dependence of the scattered intensities on the direction of the polariton wave vector k p. The measurements have been performed with BeSO4...
Phonon polaritons are hybrid states of light and matter that are typically realised when optically active phonons couple strongly to photons. We suggest a new approach to realising phonon polaritons, by employing a transverse-pumping Raman scheme, as use
