Abstract :
The change of responsivity with applied bias voltage of an InGaAs/InP modified charge compensated uni-traveling carrier photodiode has been studied over a wide range of input wavelengths. The measured wavelength-dependence suggests that the primary reasons for the observed characteristics are both the Franz-Keldysh effect and impact ionization. Based on the experimental results we estimated a photodiodepsilas low-frequency third order intercept point (IP3) of 61 dBm when choosing an appropriate input wavelength.
