Optical Amplification in Avionic Analog Photonic Links

Abstract

We have described cases where the penalties incurred in IMDD links by utilizing EDFAs can be quite small or negligible. These conclusions are particularly important for short-length high-optical-power links, such as can be used in an avionic platform. These results relax the output-power requirements on low-noise lasers. In addition, this work demonstrates the significance of a new class of EDFAs, namely, EDFAs in compact flight-qualified packages having low noise figure in deep saturation
