RAMAN AMPLIFICATION AND SUPERLUMINAL PROPAGATION OF ULTRAFAST PULSES BASED ON LOOP SILICON WAVEGUIDES: THEORETICAL MODELING AND PERFORMANCE

In this paper, we report, for the first time to the best of our knowledge, the detailed modeling and performance of Raman amplification and superluminal propagation of weak ultrafast femtosecond optical pulses in nonlinear loop single mode silicon-oninsul
