Abstract:In this paper, we experimentally demonstrate a lowpower, broadband, and narrow linewidth SBS-FWM OFC with tunable line spacing of 50 to 600 GHz. The SBS-FWM OFC spans a bandwidth of ≈100 nm over the C+L-band region using ≈15 dBm pump power. The OFC is obtained by cascaded FWM process in highly nonlinear fiber (HNLF), seeded by SBS pumps in an all-fiber ring cavity setup. The linewidth of the SBS-FWM comb lines is measured to be ≈20 MHz which is largely determined by the SBS pump properties. By using the optica… Show more
