By finding the bias voltage V one can track the optimum bias, VRF-max, for maximum RF efficiency. This concept suggests a new approach to dynamically control the modulator bias for maintaining maximum RF link gain under changing operation conditions. In this work we show that V dynamically tracks VRFmax and thus can be used for controlling the modulator bias voltage for maximum RF efficiency. InGaAsP-InP Franz-Keldysh effect waveguide modulators are used in the measurements.
