Interplay between Raman scattering and four-wave mixing in As_2S_3 chalcogenide glass waveguides

Gai, Xin; Choi, Duk-Yong; Madden, Steve; Luther-Davies, Barry


We have studied parametric amplification in dispersion-engineered As2S3 waveguides achieving a highest gain of over þ35 dB using a pulsed pump. The gain is shown to involve an interaction between stimulated Raman scattering (SRS) and four-wave mixing (FWM). The gain was studied both experimentally and using computer modeling, which revealed that SRS contributes over þ20 dB to the combined gain and significantly modifies the dependence of the FWM the conversion efficiency as a function of...[Show more]
