… mode beating), and the timing jitter of the optically generated pulses by setting the dc-bias
current from 150 mA to 450 mA . The timing jitter … a 450-m-long single-mode fiber (SMF) [1]. …

… only by 1 dB or less in two times FWHM spectral overlap for each beat note. This indicates
slight changes in overlap is not a noticeable issue in our method for timing jitter measurement. …

… beat-tone signals from a mode-locked laser operating under optical injection. From the
synchronized mode-beating signals, the integrated timing jitter … the longitudinal-modes is studied. …

… The CEO beat note and its mirror frequency are clearly … noise level with respect to the CEO
beat signal but does not improve the … In some early experiments, we observed that this beat …

… By offsetting the synthesizer frequency and reducing the photodiode signal to a level that
eliminates harmonics of the beat frequency, we obtain linear operation. A low-pass filter …

… varies linearly in time, k = Aut, and we have no mode locking, only a beat frequency Aw. Due
to relative phase noise one cannot observe this beat. With modulation the beat frequency is …

… to measure the timing jitter spectral density … timing delay configuration using a 325 m long
timing-stabilized fiber link enables the characterization of timing jitter faster than the delay time. …

… centered at mυr, each harmonics corresponds to the beating between a pair of modes
separated by m-1 modes in the optical spectrum. At any given value of m, each harmonics will …
