ABSTRACT:
Chitosan-based electro-optic elements are disclosed. An optical waveguide is made from films of chitosan-acetic acid, and from films of chitosan-acetic acid doped with various rare-earth metal ions, over a substrate. Optical limiters are made from chitosan gel host materials doped with a variety of photo-interactive or light limiting dopants. Three different suitable example chitosan gel hosts are disclosed. An electrostatically self-assembling multilayer film is made with a chitosan base layer.
