Paper Abstract

We present current work developed at INO on phosphate glass optical fiber for laser and amplifier applications at 1.54 microns. Core and cladding glasses were fabricated by a multi-components melting process which gave an uniform refractive index core profile. Rod-in-tube method under Argon atmosphere was used to fabricate optical fibers. The effect of nitrogen atmosphere on hydroxyl groups OH- during glass melting was studied. The absorption coefficient calculated at 3.42 μm was found to be lower than 0.5 cm-1 which corresponds to less than 70 ppm OH-. Absorption and emission cross sections were calculated at 1534 nm. Fabrication process allowed us to decrease background losses of core Er3+ - Yb3+ co-doped fiber between 0.02 and 0.04 dB/cm. Laser power was measured at 1563 nm and a 26% slope efficiency was achieved with a 22 cm-long single-clad fiber co-doped with 1.1 wt% in Er3+ and 11.1 wt% in Yb3+. For the same fiber, an internal gain was found to be 20 dB at 1536 nm for a 5-cm-long fiber.
