Differential electro-absorption modulator systems

Abstract

An electro-optic integrated circuit includes: an electroabsorption modulator (EAM); and a signal driver and a bias circuit; wherein the EAM includes a first EAM section configured to generate a first modulated optical output signal from an optical input signal; and a second EAM section optically coupled to the first EAM section and used to receive the first modulated optical output signal and output a second modulated output signal; wherein the first EAM section and the second EAM section are each used to receive substantially out-of-phase differential signals from the signal driver and the bias circuit to generate substantially in-phase modulation in the EAM.
