Abstract

We present a new design of dispersion flattened optical fiber for flat nonzero dispersion in the S-band region. The optimized parameters of optical fiber are used to find the optimum concentration of Tm-ions in Tm-doped optical fiber, which is further analyzed for the gain and noise performance. It is found that about 5000 mW of pumping power at 1.064 <i>µ</i>m is required to obtain 15 dB gain at 1.47 <i>µ</i>m in the silica glass Tm-doped (dispersion flattened) optical fiber.
