Investigation of optical gain in Al2O3:Er channel waveguide amplifiers
Abstract
Reactively co-sputtered aluminum oxide layers with low background loss and varying Er concentrations have been deposited. Net optical gain of 0.76 dB/cm was obtained for an Er concentration of 0.9×1020 cm -3 in a channel waveguide. © 2008 Optical Society of America.
