文摘

Yb³⁺/Er³⁺ codoped fluorophosphate glass has been investigated for developing broadband waveguide amplifier application. Spectroscopic properties and energy transfer microparameters of prepared glasses have been discussed. The spectral components of 1.55 渭m emission are analyzed and an equivalent four-level system is proposed to estimate the stark splitting for the ⁴I_15/2 and ⁴I_13/2 levels in Er³⁺ doped fluorophosphate glass. The results indicate that highly doped Yb³⁺ ions could transfer energy to Er ions efficiently in fluorophosphate glass and Er³⁺/Yb³⁺ doped fluorophosphate glass is preferable for broadband Er³⁺-doped waveguide amplifier application.
