Optical gain at 1535 nm in LaF_3:Er,Yb nanoparticle-doped organic-inorganic hybrid material waveguide

摘要

LaF_3:Er,Yb nanoparticle-doped organic-inorganic hybrid material waveguides were demonstrated using reactive ion etching technology. The absorption and photoluminescence spectra were observed on a 140 μm thick film of the nanoparticle-doped hybrid material. Under excitation at 976 nm, the fluorescence was obtained at 1535 nm, and its full width at half maximum was about 83 nm. A relative optical gain of about 5 dB was measured at 1535 nm in a 22-mm-long waveguide.
