We show analytically as well as experimentally a photonic technique for generation of frequency-tunable microwave signals. The technique involves propagating an array of uniformly spaced optical combs with identical comb ...

An optoelectronic oscillator (OEO) with wideband frequency tunability and stable output based on a bandpass microwave photonic filter (MPF) has been proposed and experimentally demonstrated. Realized by cascading a finite ...

We experimentally demonstrate pulse energy enhancement in an all-fiber passively mode-locked laser operating in the large normal dispersion regime. By increasing the laser cavity length as well as its net cavity dispersion, ...

In this paper, we show experimentally for the first time a 2 GSamples/s optically sampled analog-to-digital converter based on dual-output modulation and balanced photodetection scheme. Linearization in the form of arcsine ...

We show analytically and experimentally that direct photodetection of a temporally-stretched and chirped optical pulse-train together with its time-delayed replica can be exploited to realize the generation of tunable ...

In this paper, we propose an approach to generate microwave pulses with wide frequency multiplication tuning range based on the unbalanced temporal pulse shaping (TPS) principle. The key to achieving a wide tuning range ...

We characterize the noise conversion from the pump relative intensity noise (RIN) to the RIN and phase noise of passively mode-locked lasers at 1.5 μm. Two mode locking mechanisms, nonlinear polarization rotation (NPR) and ...

Pump relative intensity noise (RIN) has been recognized as a major source of noise in mode-locked lasers. The coupling of RIN from the pump to the output of a passively mode-locked fiber laser (PMFL) is systematically ...

The frequency response of the noise conversion from the relative intensity noise (RIN) to the phase noise in the photodetection process of an optical pulse train is characterized with pump modulation method. It is found ...

In this paper, we show analytically for the first time that spectral-filtering a supercontinuum source into equally-spaced optical combs with identical comb profile can lead to the generation of frequency-tunable microwave ...
