The goal of this project is to develop new high performance Er/Yb-codoped phosphate glass cladded fibers for fabrication of miniature high efficiency lasers and amplifiers for 1.54 ?m optical communications systems. Kigre's highly developed MM-1, MM-2, and QX/Er Er/Yb-codoped phosphate glasses are well suited for use as 1.54 ?m oscillator amplifier materials. This Phase I effort will focus on the design, fabrication, and initial evaluation of a novel single mode clad fiber capable of producing high gain amplification (~0.5 dB/mm) at 1.54 ?m in a short (~3-4cm) length.
