Time Domain Numerical Study of Two Semiconductor Optical Amplifiers Laser Cavity Structures

In this paper, we develop a time domain model of a Semiconductor Optical Amplifiers Fiber Cavity Laser (SOA-FCL). The time domain characteristics of two different cavity configurations (bidirectional and one-way cavity) are compared. The study shows that one-way cavity is less noisy compared to the bidirectional cavity which presents higher output power.
