Abstract
We report a novel differential, integrated optical receiver which is c apable of generating symmetric, complementary data signals at the prea mplifier stage. The receiver offers superior bandwidth and common mode noise rejection over the conventional transimpedance receiver. A wide -bandwidth receiver implementation in which an InGaAs p-i-n photodiode is dc coupled between a pair of current-source circuits embedded in a GaAs/AlGaAs HBT preamplifier IC is demonstrated.
