Abstract

We report the spectroscopy of crystalline waveguide amplifiers operating in the telecom C-band. Thin films of erbiumdoped gadolinium lutetium potassium double tungstate, KGd_xLu_yEr_1-x-y (WO₄)₂, are grown by liquid-phase epitaxy onto undoped potassium yttrium double tungstate (KYW) substrates and micro-structured by Ar⁺-beam etching. Channel waveguides with erbium concentrations between 0.45-6.35 × 10²⁰ cm^-3 are characterized. The transition cross-sections of interest are estimated. The effect of energy-transfer up-conversion (ETU) is experimentally investigated. Microscopic and macroscopic ETU parameters are extracted from a simultaneous analysis of 20 decay curves of luminescence on the transition ⁴I_13/2 → ⁴I_15/2. The correlation between ETU and the doping concentration is studied. Pump excited-state absorption (ESA) on the transition ⁴I_11/2 → ⁴F_7/2 is investigated via a direct ESA measurement using a double-modulation pump-probe technique. The effect of ESA is studied for different pump wavelengths. The pump wavelength of 984.5 nm is found to be favorable for the complete range of erbium concentrations.
