Paper Abstract

Tellurite waveguides are promising candidates for high gain with broad-bandwidth, especially with Er-doping, which covers the telecommunications band and important spectral absorption features of atmospheric CO2. This study aimed at developing new Er,Yb-doped tellurite waveguide power amplifier modules suited to LIDAR measurements from space that will enable improved mapping of the concentration and distribution of CO2 in our atmosphere. A comparison of the optical properties of bulk and waveguide samples has been made, with double-clad waveguide devices, suited for high power diode pumping, currently under test.
