Semiconductor Optical Amplifiers in avionics [PDF]
2011 IEEE Avionics, Fiber- Optics and Photonics Technology Conference, 2011 RSOAs have been demonstrated to operate within a WDM PON architectures over a >;60nm wavelength range with large path loss capabilities. Two RSOAs enable contiguous operation over the S, C and L bands; results indicate clearly that WDM architectures suitable for avionics with a PLC of >;25dB are possible with only two devices.

Dynamics and its Effects on Saturation Region in Semiconductor Optical Amplifiers
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2021 We focus on studying the dynamics of bulk semiconductor optical amplifiers and their effects on the saturation region for short pulse that differ, however there is the same unsaturated gain for both dynamics.
