(a) Experimental setup. (b) Output spectral density (color scale, dB) from the HNLF as a function of seed delay (avg. pump power $\sim 14\mathrm{mW}$). (c) Spectral density vs wavelength (horizontal sections from b) at seed delays of (bottom to top) $-48\mathrm{ps}$, $-26\mathrm{ps}$, 12 ps, and $-1\mathrm{ps}$ (note fine structure). Curves offset by 15 dB, dashed lines at $-60\mathrm{dB}$ levels. Seed spectrum (gray, bottom trace) is superimposed on noise-induced MI lobe. (d) Spectral density vs seed delay at different spectral regions (vertical sections from b). By wavelength: BP 1545 (band pass, $\Delta \lambda \sim 3\mathrm{nm}$), LP 1640 (long pass), SP 1448 (short pass), BP 1672 ($\Delta \lambda \sim 1\mathrm{nm}$).Reuse & Permissions

(a) Simulated output spectral density [dB, color scale as in Fig. 1b] from the HNLF as a function of seed time delay. (b) Schematic diagram of features contained in spectral maps of Figs. 1b, 2a. (c) Simulated output spectral density (color scale, dB) from the HNLF as a function of seed center wavelength (seed delay $\tau =0$).Reuse & Permissions

Figure 3

Measurement of SC spectral density vs wavelength as a function of relative seed (a) and average pump power (b). Dotted lines label the soliton peak. (c) Representative experimental RF spectra for band pass-filtered seeded and unseeded supercontinua with same average redshifted power. (d) Measurement of band pass-filtered SC output power ($\lambda \sim 1685\mathrm{nm}$, $\Delta \lambda \sim 8\mathrm{nm}$) vs average pump power (left axis). Measured RF noise reduction from unseeded to seeded SC vs band pass-filtered power (right axis). Pump power adjusted for unseeded case to keep the band pass-filtered power the same.Reuse & Permissions
