Abstract

The emission properties of Yb³⁺/Ho³⁺-codoped antimony-silicate optical fiber has been investigated. Luminescence at 2.1 μm corresponding to ⁵I₇→ ⁵I₈ transition in holmium was obtained by energy transfer between Yb³⁺ and Ho³⁺ ions. According to the Dexter-Miyakawa model, the parameters of energy migration C_DD of the ²F_5/2 (Yb³⁺) ↔ ²F_5/2 (Yb³⁺) transition and direct energy transfer C_DA of the 2F5/2 (Yb³⁺) → ⁵I₆ (Ho³⁺) transition was calculated. The optimization of the activator content and the concentration ratio were conducted with the purpose of maximizing the efficiency of energy transfer. It made possible to select best-suited glass which was used to manufacture double-clad optical fiber. Strong and narrow bands of spontaneous emission which formed as a result of energy transfer between ytterbium and holmium ions were observed in the fiber under exciting with radiation at 978 nm wavelength.
