Tm3+-doped tellurite glass for a broadband amplifier at 1.47 mu m

摘要

Tm3+-doped tellurite glass is investigated as a host for a broadband amplifier at 1.47 mu m. The Tm3+ fluorescence spectrum, lifetime, and cross section in tellurite glass are compared with those in fluorozirconate glasses. The advantages of a Tm3+-tellurite amplifier, especially when it is employed in combination with an Er3+-tellurite 1.55-mu m amplifier, are discussed.
