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. Â© 2007 American Institute of Physics.
