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.
