HIGH SPEED DIFFERENTIAL OPTOELECTRONIC RECEIVER

摘要

A high speed differential optoelectronic receiver comprises a first photodetector responsive to a first incident amplitude modulated optical signal and operative to develop a first electrical signal, a second photodetector responsive to a second incident amplitude modulated optical signal that is complementary to the first optical signal and operative to develop a second electrical signal, and an amplifier having a first input that is responsive to the first electrical signal and a second input that is responsive to the second electrical signal and is operative to provide a differential output signal that is proportional to the difference between the first and the second electrical signals. Also, a method for transforming complementary amplitude modulated optical signals into a complementary electrical output signal is invented.
