Thulium-Doped Fiber Amplifier, Numerical and Experimental Approach 

Due to the tremendous increase in communication traffic in recent years, more and more efforts in research have been directed towards developing highly efficient broad-band fiber amplifiers that will fully exploit the low-loss band of silica fibers in order to increase the transmission capacity of wavelength-division multiplexing (WDM) networks. These broad-band amplifiers must be able to amplify the new short wavelength band (S-band) in addition to the existing C- and L-bands. Thulium-doped fiber amplifiers (TDFAs) are a promising candidate for the S-band amplification. This book reviews TDFA’s structure and its amplification mechanism.
