Abstract :
This study demonstrates wavelength conversion and intrinsic Raman amplification. This work shows that phase matching is required to achieve high conversion efficiencies. In addition, reduction of waveguide cross section, while maintaining low propagation loss, is highly desirable for both wavelength conversion and optical amplification. The resulting increase in light intensity enhances the Raman interaction and the reduction in free carrier lifetime diminishes the two-photon absorption-induced free carrier losses.
