Abstract

A method is described to separately determine the contributions from the third-order nonlinearity and from the linear electro-optic (EO) effect in EO polymer system under dc biased poling conditions. An experiment was carried out using a dc biased, controlled temperature technique in a waveguide Mach-Zehnder modulator. The drive voltages of the EO device were measured at various bias voltages and temperatures. Based on these data, it is found that the modulation of the device is predominantly due to the linear EO effect and the contribution from the third-order effect was not significant when the chromophores are effectively aligned in strong bias fields and at temperatures close to the glass transition temperature of EO polymer.
