Small-Signal Analysis of the Voltage-Dependent Nonlinearity in High-Power Uni-Traveling-Carrier Photodiodes

초록

It is demonstrated with small-signal analysis how the voltage-dependent responsivity in the uni-travelling-carrier photodiode (UTC PD) can lead to the intermodulation distortion. A simple expression for the third-order output intercept point (OIP3) is derived and compared with experiments. Reasonable agreements between the theoretical and experimental OIP3 values are observed. (c) 2013 The Japan Society of Applied Physics
