Paper Abstract

The full potential of second-order nonlinear polymers can be utilized in electro-optic polymer modulators with a DC biased operation scheme to greatly reduce the half-wave voltage. This technique makes use of the total achievable electro-optic coefficient, which can be more than three times the value that is used by the conventional devices of poled electro-optic polymer. As the result of the DC bias and with high-?? chromophores, a low half-wave voltage of 1.5 V was achieved with 2-cm-long birefringent waveguide modulators at the wavelength of 1.3??. Results of a 200°C stability experiment indicate that this scheme also enables electro-optic polymer devices to meet the short-term high- temperature stability requirement because the polymer does not need to be poled prior to high-temperature steps.
