- Abstract
The all-optical waveguide theory based on photoisomerization nonlinear effects is systematically and deeply studied, and a nonlinear holographic all-optical waveguide scheme is proposed for the first time. It is found that the induction of a light with stronger isomerization activity on the material weakens the self-defocusing effects of the signal light. Especially, polarization states of both inducing light and signal light also unexpectedly affect propagation of signal light. Part of the theoretical results has been qualitatively confirmed by Z-scan experiments. The proposed holographic all-optical waveguide scheme means polarization information is applied in the all-optical waveguide besides intensity information. Compared with the traditional all-optical waveguide, the performance of holographic waveguide will be greatly improved, making the control of light more precise and easier. Such nonlinear waveguide scheme may find its application in the future all-optical net.
