Electro-Absorption-Transceiver (EAT) structures used as efficient Travelling-Wave Electro-Absorption-Modulator (TWEAM) as well as Travelling-Wave-Photo-Detector (TWPD) are investigated. Clear eye-openings at 100Gb/s for operation as modulator and/or as detector, as well as 80Gb/s transmission between a pair of EATs, are presented.
