ABSTRACT:
This invention provides a fiber waveguide with a liquid crystal core. The liquid crystals are aligned in layers with molecular directors approximately parallel to each other. An electric field can be applied to the liquid crystal core to provide linear and nonlinear optical modulation. Alone or in combination with polarizers, reflectors, and birefringent elements, the waveguide of this invention provides phase, polarization and intensity modulation, spectral filtering, and second harmonic generation.
