   Abstract:
   The Langmuir-Blodgett-Kuhn (LBK) room-temperature method for making non-linear optical (NLO) polymer films is investigated. A Mach-Zender interferometer by the LBK method is made for optical modulation, demonstrating that useful devices are made from relatively thick, room-temperature-deposited NLO polymer films. The LBK method is convenient for fabricating films from large, temperature-sensitive, even ion-containing chromophores that is difficult to align by electric-field poling. At high temperatures, the electric conductivity of the film is so high that the field across the film is not adequate to give a high degree of polar order.
