摘要：

The Letter shows that the common-mode rejection ratio of balanced photodetector pairs, as used for coherent lightwave reception, is insensitive to capacitance differences between the detectors in the absence of parasitic series impedance. These results indicate that balanced performance can be achieved in high-speed detector pairs, even when a capacitance imbalance occurs. The effect of detector series resistance or inductance on common mode rejection is quantitatively analysed.
