Third-order intermodulation distortion in an InGaAs/InP charge compensated modified uni-traveling carrier photodiode is characterized using a two-tone setup. Plots of the third-order local intercept point (IP3) versus photocurrent exhibit peaks. A simple analytical model is developed which explains that the peaks are due to the interaction of voltage-dependent and photocurrent-dependent capacitance effects.
