Abstract
High-concentration Er3+/Yb3+ co-doped silica waveguide amplifiers are numerically analyzed, With optimized rare-earth concentrations the eff ect of Er3+/Er3+ ion-pairs can be neglected and each Er3+ ion be assum ed to be paired only to the surrounding Yb3+ ions, The rate-equations model includes uniform upconversion mechanisms from I-4(13/2) and I-4( 11/2) erbium levels and an Yb3+ to Er3+ pair-induced energy transfer p rocess. Numerical results demonstrate the possibility of fabricating s hort- and high-gain integrated optical amplifiers; it is shown that ne t gain as high as 3 dB/cm can be obtained.
