Strong field poling of multipolar structures: fundamentals and device implications

Summary form only given. We show that a departure from the low field value of the nonlinear anisotropy can be obtained in strong poling field conditions. Such possibility of controlling the nonlinear anisotropy ratio has been experimentally evidenced for different values of the corona poling field in the case of polycarbonate matrices doped with the DR1 dipolar chromophore and the multipolar dinitro-di-(n-butylamino)-benzene (DNDAB) compound. As the poling field remains in the range of currently used values for electro-optic devices, the possibility to achieve polarization independence by use of mullipoiar molecules becomes a realistic target.
