Photonic generation of frequency-tunable microwave signals using an array of uniformly spaced optical combs
(2012)
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 optically tunable wideband optoelectronic oscillator based on a bandpass microwave photonic filter
(2013)
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 ...
High-energy dissipative soliton with MHz repetition rate from an all-fiber passively mode-locked laser
(2012)
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, ...
Linearization of an optically sampled analog-to-digital converter
(2012)
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 ...
Photonic generation of tunable continuous-wave microwave signals using a temporally-stretched and chirped pulse-train
(2012)
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 ...
Photonic generation of microwave pulses with wide frequency multiplication tuning range
(2012)
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 ...
Noise conversion from pump to the passively mode-locked fiber lasers at 1.5 μm
(2012)
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 ...
Nonlinear coupling of relative intensity noise from pump to a fiber ring laser mode-locked with carbon nanotubes
(2010)
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 ...
Frequency response of the noise conversion from relative intensity noise to phase noise in the photodetection of an optical pulse train
(2011)
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 ...
Frequency-tunable millimeter-wave generation technique based on spectral-filtering of a supercontinuum source
(2012)
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 ...
