A new photonic approach of microwave waveform generator based on time-domain synthesis is proposed and experimentally demonstrated, in which two single-drive Mach-Zehnder modulators biased at quadrature point are severed as optical pulse carvers various waveforms can be generated by carving overlapping field envelopes. The theoretical analysis simulation developed. In experiment, a square with 50% duty cycle, triangular full sawtooth (or reversed-sawtooth) cycle generated. Furthermore, frequency doubling also obtained.
