Fig. 6 — Schematic of the OCT setup (a) [L_i lens, M mirror, DM dichroic mirror, and PC polarization controller]. Normalized power spectral density (PSD) profiles measured using an OSA (red curves, right axis) and RIN profiles (black circles, left axis) for the 320 MHz SuperK extreme (b), the 80 MHz SuperK extreme (c), and the ANDi based low-noise SC source (d). Calculated dispersion profile for the nonlinear fiber used in the SuperK extreme (blue) and the measured dispersion of the GeO₂ doped silica ANDi fiber (red) (e). Mean OCT-amplitude (over 1024 measurements) of a sample mirror at 20 different axial positions on the left axis, and the sensitivity on the right, for the SuperK extreme at 320 MHz (f) and 80 MHz (g), and the ANDi based low-noise SC source (h)
