Paper Abstract

Electro-optically active planar waveguides of aromatic polyurea were prepared by simultaneous deposition of 4,4'-diamino-diphenyl-methane and 4,4'-diphenylmethane- diisocyanate from the vapor phase and subsequent corona poling. Attenuated total reflectance spectroscopy of the waveguide modes of the polymer films was used to measure the piezoelectric and electro-optic susceptibilities. It is found that the electro-optic response is not only determined by the nonlinear polarizability of the urea groups but also from their dipolar orientation in the applied field.
