Abstract

Bulk second order optical nonlinearity in organic polymers containing hyperpolarizable dye molecules is normally created by electrostatic field poling at elevated temperature, where the electric field induces a polar alignment of the dyes. In contrast to this approach, we have used asymmetric injection of electric charge into the polymer to create bulk nonlinearity in the polymer [1]. We show that the charge injection mechanism is fundamentally different from dipole alignment of the dye, and has both similarities and differences to poling of glass.
