Research Topics


Under the proposed project, Photon-X will demonstrate the feasibility of a compact, optically pumped, high gain, erbium perfluoro polymer optical fiber amplifier having low-loss at 1550 nm for operation in short and medium distance data communications network systems. The polymer amplifier will be based on the recent discovery at Photon-X of high performance rare earth polymer materials. The new rare earth polymers are directly synthesized at high rare earth ion concentrations (>10% wt of rare earth ion) with each metal ion encapsulated and physically buffered by insulating, covalently bonded, perfluorinated ligands that then form the polymer backbone matrix. This is distinctly different from heavily studied inorganic glasses and single crystals where rare earth ion salts are doped directly into the host but only to relatively low levels (
