Fabrication Of Laf3:Er,Yb Nanoparticle Doped Organic-Inorganic Hydrid Material Waveguide Amplifier And Its Properties

LaF3 : Er, Yb nanoparticles doped organic-inorganic hydrid material waveguide amplifier is fabricated. The optical gain and upconversion in the waveguide are studied. The upconversion emission bands at 405,520,544 and 650 nm are assigned to H-2(9/2) -> I-4(15/2), H-2(11/2) -> I-4(15/2) , S-4(3/2)-> I-4(5/2) and F-4(9/2) -> I-4(15/2) transitions, respectively. The possible upconversion mechanism of Er3+ in this material was analyzed. A 1.55 dB/cm relative gain was observed when pumped by a 976 nm laser at 160 mW power.
