Numerical Modeling of CW Raman Amplification in Integrated TeO2 Waveguides

We report on numerical investigation of Raman amplification in integrated tellurite (TeO 2 ) waveguides. Our numerical results show possibility of an integrated Raman amplifier with expected gain above 2 dB at low propagation loss of 0.01 dB/cm and 1 W pump power in a 20-cm-long TeO 2 -coated Si 3 N 4 waveguide.
