Abstract
A new photonic approach for generating a triangular waveform with octupled frequency, to the best of our knowledge, is presented. The core principle is the frequency octupling technique based on two cascaded dual-parallel Mach—Zehnder modulators(MZMs). A dual-electrode MZM and a single-mode fiber are subsequently applied to manipulate the signal spectrum to satisfy the characteristics of a triangular waveform. By applying a 2 GHz radio frequency signal, a full-duty-cycle triangular waveform with a repetition rate of 16 GHz is obtained. The high-frequency multiplying factor shows great potential in generating a cost-effective waveform. Additionally, the phase imbalance of a hybrid coupler and bias drift of the MZM have been considered in our simulation, which further verify the feasibility and stability of our proposal.
