[Abstract]:An optical generation scheme for triangular wave signals based on optical adjustable dispersion is proposed and verified by experiments. The local oscillator signals drive one arm of the two-electrode Mach-Zehnder modulator DE-MZM, and modulate the CW CW laser to produce each order optical sideband. By reasonably setting the DC bias point of the DE-MZM, and using the adjustable dispersion compensator to introduce a certain phase shift to the optical signal, The triangular wave signal with the same repetition rate as the local oscillator signal can be obtained by photoelectric detection. By simply changing the frequency of Lo signal, the repetition rate of triangle wave signal is changed accordingly. In the experiment, the triangle wave signals with repetition rate of 5GHz and 6GHz are obtained by using the scheme in this paper. In this paper, the scheme is simple, the frequency tuning is flexible, and the triangle wave signal with repetition rate up to 40GHz can be obtained by using the existing commercial optoelectronic devices, which can meet the application needs of the future high-frequency electronic system.
