In this paper, a photonic microwave waveform generator based on a dual-parallel Mach–Zehnder modulator is proposed and experimentally demonstrated. In this reported scheme, only one radio frequency signal is used to drive the dual-parallel Mach–Zehnder modulator. Meanwhile, dispersive elements or filters are not required in the proposed scheme, which make the scheme simpler and more stable. In this...
We propose time delay division DFT-S FDMA PON scheme. Each ONU can receive data by using AdCs of 1/2∼1/32 Nyquist Sample Rate such that DFT and IDFT are unnecessary for de-mapping and picking out signals.
A new single-mode optoelectronic oscillator (OEO) with three coupled cavities is proposed and demonstrated. A Fabry-Perot (F-P) cavity fiber laser and an optical-electrical feedback branch are coupled together to construct an optoelectronic oscillator, where the F-P cavity fiber laser serves as a light source, and a modulator is placed in the laser cavity to implement reciprocating modulation, which...
