Paper Abstract

Er3+-Yb3+ co-doped phosphate glass waveguide amplifier at large signal operation are theoretically studied. By solving the rate and optical power propagation equations describing the Er3+-Yb3+ co-doped system, quantum conversion efficiency(QCE) at large operation are optimized. It is shown that improvement of Er3+-concentration and increase of amplifier length can improve QCE, improvement of Yb3+-concentration reduces QCE, the rate of 1~2 of Er3+-Yb3+ co-doped concentration is available.
