Abstract
Photo-anisotropic effects are useful for many photonic applications such as optical storage[1,2], optical switch[3,4], optical waveguide[5,6], optical display[7] and optical limiter[8]. However, several factors such as molecular movement and electrostatic interactions reduce the photo-anisotropy effects[9]. We report a technique for significant enhancement of photoanisotropic effect using two laser beams with orthogonal polarization resulting in optimization of molecular anisotropic distribution. We also demonstrate an all-optical switch with the novel feature of output sign-control.
