Abstract :
Summary form only given. Dy/sup 3+/-doped materials have been proposed for optical fibre amplifiers at 1.3 μm. Dy/sup 3+/ has several advantages over Pr/sup 3+/-based amplifiers for 1.3-μm telecommunication applications. First, numerous pump bands exist in the near-IR for populating the (/sup 6/H/sub 9/2/, /sup 6/F/sub 11/2/) level. Secondly, these pump bands have absorption coefficients >10 times that of the Pr/sup 3+/ /sup 1/G/sub q/ level in the same host.
