Paper Abstract

In this paper, we report a novel technique that combines push-pull Mach-Zehnder modulator structure with dc bias to achieve fractional volt half-wave voltage in intensity modulation. The technique is accomplished by simultaneously applying a common mode operation voltage and a differential dc bias voltage on the two arms of a Mach-Zehnder modulator. The modulators are tested for half-wave voltage at different temperatures while applying different push-pull biases. The results are compared with a push-pull EO polymer modulator that has identical dimensions and the same materials, and which is fabricated and poled with conventional method. It is found that our new approach reduces the half-wave voltage by a factor of more than five.
