    Abstract: A borosilicate glass composition comprises SiO2 having a concentration of about 40 mole percent to about 60 mole percent, B2O3 having a concentration of about 10 mole percent to about 30 mole percent, and an alkaline earth and/or alkali compound having a concentration of 10 mole percent to about 40 mole percent. An optical fiber amplification device comprises a borosilicate glass material cladding. The core comprises a germanate glass material doped with Tm3+. The germanate glass material has a first surface configured to receive an optical signal having a wavelength of from about 1400 nm to about 1540 nm and a second surface configured to output an amplified optical signal. In this manner, low cost fiber amplifiers in the 1450-1530 nm wavelength region (corresponding to the S-band) can be achieved.
