Sol–gel-derived planar waveguides of Er3+:Yb3Al5O12 prepared by a polyvinylpyrrolidone-based method

Erbium (Er 3+ )-doped ytterbium garnet [(Er x Yb 1- x ) 3 Al 5 O 12 ; x  = 0.005, 0.02 and 0.1, YbAG] planar waveguides have been prepared by an aqueous sol–gel method using polyvinylpyrrolidone as a gelling agent. The thermal behavior of gel was studied by thermogravimetry and differential thermal...

Description
Summary:Erbium (Er 3+ )-doped ytterbium garnet [(Er x Yb 1- x ) 3 Al 5 O 12 ; x  = 0.005, 0.02 and 0.1, YbAG] planar waveguides have been prepared by an aqueous sol–gel method using polyvinylpyrrolidone as a gelling agent. The thermal behavior of gel was studied by thermogravimetry and differential thermal analysis. The phase composition of the films was determined using X-ray diffraction. Surface analysis was carried out by atomic force microscopy. A pure infrared emission of Er 3+ ions was observed in all prepared films. Light propagation was studied by m-line spectroscopy using several wavelengths (633, 964, 1311 and 1552 nm). The minimum coating cycles to observe one propagated mode at 1552 nm were determined to be 7. The sol–gel-derived Er:Yb 3 Al 5 O 12 seems to be a promising material for light amplifiers in the IR region. Graphical Abstract
