Abstract

Spectroscopic properties of 1.6 μm emission from Ho³⁺-doped sulfide glass were evaluated for their potential use as U-band fiber-optic amplifiers. Emission from the ⁵I₅→⁵I ₇ transition showed a peak wavelength of 1670 nm and a full width at half maximum of ∼65 nm with a cross-section of ∼7.1×10 ^-21 cm². Ho³⁺ concentration in glass should be limited to 0.08 mol% due to energy transfers between Ho³⁺ ions which lead to a decrease in the ⁵I₅ level lifetime. Co-doping of Tb³⁺ effectively decreased terminal ⁵I₇ level lifetimes via the energy transfer of Ho³⁺:⁵I ₇→Tb³⁺:⁷F_{0, 1, 2}.
