The visible and near infrared emission spectra of Er3+-Tm3+- codoped tellurite glasses and fibres were measured with the excitation of an 800 nm laser. A broad emission extending from 1.35 µm to 1.6 µm with a full width at half-maximum (FWHM) of ~160 nm was recorded in a 24 cm long 0.2 wt% Er2O3 and 1.0 wt% Tm2O3 codoped tellurite fibre. Energy transfer between Er3+ and Tm3+ play important roles in the luminescence mechanism. These results indicate that Er3+-Tm3+ codoped tellurite fibre could be a promising material for broadband light source and broadband amplifier for the wavelength-division-multiplexing (WDM) transmission systems.
