Abstract
The chapter presents a concept for an ultra-broadband bidirectional dual-band quantum-dot semiconductor optical amplifier (QD SOA). This device can considerably simplify the network architectures and thus can increases the power budget of the network. The experimental prove of concept is demonstrated in 40 GBd on-off keying (OOK) single-channel dual-band configuration. The input-power dynamic range (IPDR) of the bidirectional signal amplification is determined and discussed in dependence of the operating parameters. Finally, simulations of the experimentally obtained results are presented allowing to gain inside into the physical properties of the device.
