Contact poling of the nonlinear optical film for polymer-based electro-optic modulator

Poling of nonlinear optical (NLO) film is an important step in building an electro-optic polymer-based modulator. In this paper, an electro-optic modulator based on disperse red 1(DR1) side chained poly(methyl methacrylate) (PMMA/DR1) nonlinear optical film is designed and fabricated using the standard very large scale integration fabrication procedures. The poling methods are discussed and the contact poling is used to poling the nonlinear optical film. The poling voltage is determined by the measurement of break- down voltage. The refractive indices change before and after contact poling is given. The electro-optical coefficient of 12pm/V is obtained.
