Demo 24-07 Polarization by Scattering

, 2001
Light is polarized when it scatters from materials like air or water. This demonstration shows some of the properties of this polarization, using the apparatus of Figure 1, in which the light beam passes through a water tank into which a small amount ...

A compact two-dimensional grating coupler used as a polarization splitter

, 2003
We demonstrate a novel polarization splitter based on a two-dimensional grating etched in a silicon-on-insulator waveguide. The device couples orthogonal modes from a single-mode optical fiber into identical modes of two planar ridge waveguides.

Polarization-insensitive wide-angle resonant acousto-optic phase modulator

Phase modulators are commonly used devices in optics. Free-space phase modulators are typically constructed from optically anisotropic crystals exhibiting the Pockels effect. To preserve the light's polarization state as it propagates through the crystal,
