Complete Noise Characterisation Of External Cavity Semiconductor Laser Hybridly Modelocked At 10 Ghz
The measurements of amplitude modulation (AM) and residual phase modulation (PM) noise for a 10 GHz modelocked laser out to Nyquist frequency offsets were presented. The peak values of the spurs around the harmonics of modelocking frequency were measured to determine whether the cavity harmonic spurs represented AM or PM noise. It was found that the quadratic dependence of spur-to-carrier ratio on harmonic number suggested that the noise in the spurs was predominantly PM noise.
