Abstract
We report on the integration of two InGaAsP-InGaAsP MQW electrosorptio n ridge modulators and an amplifier on the same active layer. The two modulators are separated by a 500-mu m ridge waveguide optical amplifi er, in order to prevent electrical crosstalk, and to compensate for op tical losses. The first modulator is used as a soliton generator, and the second codes the generated pulses. The amplifier showed 8.2-dB gai n for 120-mA injected current. This allowed a low fiber to fiber inser tion loss of 9 dB for the tandem. We present here for the first time t o our knowledge, a 20 Gbit/s operation for a tandem-amplifier device, together with transmission experiments.
