Experimental–Simulation Analysis of a Radiation Tolerant Erbium-Doped Fiber Amplifier for Space Applications by Alberto Facchini, Adriana Morana, Luciano Mescia, Cosimo Campanella, Md Mizan Kabir Shuvo, Thierry Robin, Emmanuel Marin, Youcef Ouerdane, Aziz Boukenter, Sylvain Girard

“…Using a home-made simulation code based on the rate and power propagation equations and including the RIA effects, the radiation-dependent performance of EDFAs were estimated. The variations in the spectroscopic parameters caused by irradiation were also characterized, but our results show that they give rise to EDFA gain degradation of about 1%. …”

Comparison of stapled haemorrhoidopexy with traditional excisional surgery for haemorrhoidal disease (eTHoS): a pragmatic, multicentre, randomised controlled trial by Watson, A, Hudson, J, Wood, J, Kilonzo, M, Brown, S, McDonald, A, Norrie, J, Bruhn, H, Cook, J, eTHoS study group

Remote temperature sensing with low-threshold-power using erbium-doped fiber laser by Jaharudin, Nurul Atika Nabila

“…A 30 km single mode fiber is placed before the FBG to serve as a transmission channel for remote sensing and erbium-doped fiber amplifier (EDFA) as the gain medium. The EDFA is used because it can operate using low pump power owing to the high gain efficiency of the doped-fibers. …”
