Electro-Optic Polymers hold great promise in increased
electro-optic coefficients as compared to their inorganic
corollaries. Many researchers have focused on quantum chemistry to
describe how the dipoles respond to temperature and electric
fields. Much work has also been done for single layer films to
confirm these results. For optical applications, waveguide
structures are utilized to guide the optical waves in 3 layer
stacks. Electrode poling is the only practical poling method for
these structures. This research takes an electrical engineering
approach to develop poling models and electrical and optical
transfer functions of the waveguide structure. The key aspect of
the poling model is the large boundary charge density deposited
during the poling process. The boundary charge density also has a
large effect on the electrical transfer function which is used to
explain the transient response of the system. These models are
experimentally verified. Exploratory experiment design is used to
study poling parameters including time, temperature, and voltage.
These studies verify the poling conditions for CLDX/APC and
CLDZ/APEC guest host electro optic polymer films in waveguide
stacks predicted by the theoretical developments.
