Fig. 2. NOL experimental results of As2Se3 fibers with the length of 1 m and 0.5 m. (a) Output power density increases with the incident power density. (b) Normalized transmission decreases with the incident intensity.
Fig. 3. Transmitted pulses under low and high incident power densities. (a) Transmitted pulses with the low incident intensity of 3.9 MW/cm2, 6.4 MW/cm2, and 8.3 MW/cm2, respectively. (b) Transmitted pulses after the SBS effect occurs with the high incident intensity of 39.9 MW/cm2, 550.0 MW/cm2, and 1163.1 MW/cm2, respectively.
