Tellurite Photonic Crystal Fiber With Er3+-tm3+ For Broadband Optical Amplifier In 1550nm

Er3+-Tm3+ co-doped tellurite photonic crystal fiber was fabricated via a stack-and-draw procedure and without using extrusion in any stage. The final fiber presents a 187 nm bandwidth of amplified spontaneous emission (ASE) intensity around 1550nm when pumped with 790nm. In this manuscript a soft-glass tube fabrication technique, using the centrifugation method, is also shown.6116Knight, J.C., Birks, T.A., Russel, P.St.J., Atkin, D.M., All-silica single-mode optical fiber with photonic crystal cladding (1996) Opt.
