Description
Summary:Nonlinear photoresponse observed in the pulsed operation of an InP/InGaAs uni-traveling-carrier photodiode (UTC-PD) is analyzed in terms of the dynamic capacitance associated with charge storage in the absorption layer. To model such an effect, a variable carrier traveling delay time which changes with operation voltage and current is introduced. Optoelectronic millimeter-wave mixing for 59.4-GHz and 600-MHz-modulated 1.55 µm optical signals was examined, and found to efficiently generate a 60 GHz up-converted signal. The characteristics are semiquantitatively explained by the dynamic capacitance model.
