The proposed research investigates about the value of Amplified Spontaneous Emission (ASE) noise power from a Multimode EDFA (MMEDFA) with different Refractive Index profiles (RIP).

摘要

The proposed research investigates about the value of Amplified Spontaneous Emission (ASE) noise power from a Multimode EDFA (MMEDFA) with different Refractive Index profiles (RIP). ASE is a prominent issue that lowers the gain and performance of optical amplifiers and in noise filtering techniques in the transmission networks of medical images. This research proposes the idea of analysing and optimizing RIP as an alternative to employ filters or isolators to reduce this ASE. At MMEDFA, different RIP are exported using simulation softwares Optifiber and Optisystem. It is found that the varying RIPs affects ASE and regulates the spreading of light within the core. In this paper, the ASE noise power of the step index profile, elevated RIP, dispersion flattened fiber (DFF) profile, dispersion shifted fiber (DSF) profile, alpha peak, and alpha dip profiles at MMEDFA is compared. EDFAs guarantee the uninterrupted and high-quality transmission of data over long distances in optical networks, which are essential for high-speed data transmission of image-rich contents such as video. So EDFA can be applied in the amplification process to enhance the quality of image transmission.
