Open Access Open Access

Abstract

Laser spectroscopy of R.E. doped fluoride waveguides elaborated by PVD technique on ZBLAN or CaF2 substrate is presented. Channel waveguides of the PZG composition were obtained photolithography process on the substrate before deposition. Nd3+ fluorescence at 1.5 μm as well as erbium fluorescence at 1.55 μm are reported including decay time dependence with R.E. concentration. Finally, we have measured a signal amplification of 3.8 dB/ cm at 1.05 μm in a 1 at% Nd-doped PZG waveguide.
