Paper Abstract

We present a simple analytical model to approximately analyze the TDFA for silica glass as well as fluoride glass based optical fibers. We have verified the validity of method using the in-house fabricated Tm-doped alumino-germano-silicate glass fiber as well as reported results for the Tm-doped fluoride glass fiber. The spectral variation of gain obtained with the silica glass fiber TDFA after pumping with pump power of 275 mW at 1064 nm showed good agreement between the simulated and the measured values. The pump power dependence of gain in the fluoride glass fibers calculated by our method also showed a good agreement with the experimental results reported. The maximum error in determination of gain was limited to 12%.
