Effects of signal seeding on long-wavelength-band Er3+-doped fiber amplifiers
A study of gain improvement in the long-wavelength band (L-band) by a seeding signal from the conventional-wavelength band (C-band) is presented. The seeding signal reduces losses through amplified spontaneous emission and supplies energy for L-band amplification in the underpumped region. Gain impr...
