Electro-Optic Properties of Self-Assembled Non-Linear Optical Polymers
Electrostatic self-assembly was used to fabricate several samples of polymers known to have non-linear optical behavior. These samples characteristics were measured with interferometry and their electro-optic coefficients determined to be on the order that of LiNbO3. The self-assembled samples are …
