Waveguided Raman and Brillouin scattering
SPIE Proceedings, 2000Raman and Brillouin spectroscopy in planar waveguides can be performed by coupling the laser beam to the waveguide with a prism and by collecting the scattered light from the front surface. Brillouin spectra, which are different for excitation in the different modes of the waveguides, can be accounted for by a model that considers the space ...

Brillouin scattering in semiconductors
1975Brillouin scattering is known to be a valuable probe of acoustic phonons in gases, liquids and solids. The effects peculiar to Brillouin scattering in semiconductors will be the subject of this chapter. The velocity of sound is determined directly from the Brillouin shift; so, generally, elastic constants and velocity anisotropy, relaxation processes ...

Two-dimensional stimulated Brillouin scattering
Physical Review E, 1994The evolution of the stimulated Brillouin scattering (SBS) instability in time and two spatial dimensions is studied analytically. An exact solution of the linearized equations governing SBS in a finite homogeneous plasma shows that this two-dimensional instability usually saturates because of the convection of the ion-acoustic wave, regardless of ...

Guided acoustic-wave Brillouin scattering
Physical Review B, 1985Forward light scattering by the thermally excited guided acoustic modes of an optical fiber produce numerous narrow lines not predicted by the usual theory of Brillouin scattering. Optical heterodyne detection has been used to resolve the scattering spectrum which begins at about 20 MHz and extends to the detection limit. A simple theory quantitatively

Brillouin Scattering Spectrometry
1979Light is scattered from homogeneous materials due to microscopic local variations in the dielectric constant, and hence index of refraction within the bulk of the material. If these variations are the result of time dependent fluctuations, the scattering will generally be inelastic due to energy transfer between the incident photons and the medium ...

During the past 20 years, since the invention of the laser, light scattering has become an increasingly powerful means of measuring the spectra of systems in thermal equilibrium. Sergio Porto played a leading role in the development of techniques to take maximum advantage of the properties of laser light in its application to light scattering, and he ...
