Integrated waveguide amplifiers based on high concentration Er3+ doped Ba Y2 F8 crystals are numerically studied by combining a full-vectorial finite element based modal analysis and propagation-rate equations. Using realistic input data, such as the absorption/emission cross sections and Er level lifetimes measured on grown crystal samples, we investigate the amplifier performance by optimizing the total Er concentration.

Abstract
Integrated waveguide amplifiers based on high concentration Er3+ doped Ba Y2 F8 crystals are numerically studied by combining a full-vectorial finite element based modal analysis and propagation-rate equations. Using realistic input data, such as the absorption/emission cross sections and Er level lifetimes measured on grown crystal samples, we investigate the amplifier performance by optimizing the total Er concentration. We predict optimum gain coefficient up to 5 dBcm and broad amplification bandwidth exceeding 80 nm with 1480 nm pumping. © 2007 American Institute of Physics.File in questo prodotto:
