Abstract

Solutions of rigid macromolecules exhibit electro-optic effects and can be used in the preparation of light switches and devices for either the modulation or deflection or both of light beams, such as the output from a laser. Representative of these macromolecules are polypeptides, such as polyleucine, polyglutamic acid, polytyrosine, and poly-gama-benzyl-L-glutamate. In general, these macromolecules are freely soluble in nonhydroxylic organic solvents and form solutions which have a high electrical resistance and low conductivity. Thus, electrostatic fields can be applied to such solutions for long periods of time in contrast to present materials which require a pulsed electric field.
