Abstract
The interest of polymers for electro-optical (EO) and related applications stems from various assets such as high modulation bandwidth, compatibility with semiconductor-based technologies, strong confinement, and low-cost elaboration techniques. Although the EO coefficients r of polymers based on the dispersed red one (DR1) template as active chromophore are sufficient for basic demonstrators (r33 = 15–20 pm/V),1 a substantial increase of r is required for the design of integrated optoelectronic devices. Furthermore, the macroscopy anisotropy of electricfield oriented polymers (r13/r33 = 1/3) contradicts the crucial requirements of polarization independence. Recent advances in molecular design toward highly efficient dipolar chromophores and multidimensional molecules could help solve these problems.
