Noise characterization of an Optical Frequency Comb using Offline Cross-Correlation
, 2016 Using an offline cross-correlation technique, we have analyzed the noise behavior of a new type of optical frequency comb (OFC), which is carrier envelope offset (CEO) free by configuration, due to difference frequency generation.
