Abstract
This paper demonstrates that in broadband networks in-line semiconductor
optical amplifiers (SOAs) beside providing system gain can also be used as
simultaneous transceivers. The SOA branching stages are studied and presented
for bus configuration. Using a steady-state model, we have made a small-signal
approximation applying an equivalent circuit for detection based on the rate
equations. The theory enables us to explain the detection functionality, the
optimal working state of the multifunctional SOA, and to analyze noise properties.
The measurements support the calculations. So the SOA-transceivers are potentially
useful in subcarrier multiplexed access systems.
