(a) First 61 sine and cosine complementary patterns measured individually with the OSA. The first pattern represents the unmodulated SLED spectrum (constant pattern) followed by pairs of sine and cosine patterns of increasing modulation frequency (decreasing modulation period). (b) Modulation amplitude of the 100 sine patterns as a function of modulation period, normalized to the highest amplitude value of the modulated pattern with lowest modulation frequency. The inset shows the measured sine patterns for three specific modulation frequencies 3.5 THz (\(\sim\) 28 nm), 0.7 THz (\(\sim\) 5.6 nm), and 0.14 THz (\(\sim\) 1.1 nm) as solid black lines together with ideal sine functions as dashed red lines.
