Using nonlinear optical networks for optimization: primer of the ant colony algorithm
Using nonlinear Erbium doped optical fiber network we have implemented an optimization algorithm for the famous problem of finding the shortest path on the map for the ant colony to travel to the foraging area.
Cavity-length optimization for high energy pulse generation in a long cavity passively mode-locked all-fiber ring laser
In order to achieve higher pulse energy in a passively mode-locked fiber ring laser, a long cavity length is commonly implemented. However, a long cavity operating in the anomalous dispersion regime also leads to pulse ...
Photonic generation of frequency-tunable microwave signals using an array of uniformly spaced optical combs
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 ...
Compact passively mode-locked fiber laser at 1.55 μm with low timing jitter of 8 fs
Mode-locked fiber lasers with low timing jitter and high repetition rate is desired for various applications including photonics analog-to-digital conversion, microwave synthesis and high-precision clock distribution. We ...
Performance study and assessment of phase noise suppression by incoherent addition in a mode-locked fiber laser system
This paper investigates the effectiveness of phase noise suppression by incoherent addition in a passively mode-locked fiber laser. Incoherent addition is achieved by using an interferometer external to the mode-locked ...
High-energy dissipative soliton with MHz repetition rate from an all-fiber passively mode-locked laser
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, ...
Photonic generation of tunable continuous-wave microwave signals using a temporally-stretched and chirped pulse-train
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 ...
Noise conversion from pump to the passively mode-locked fiber lasers at 1.5 μm
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 ...
An optical fiber network oracle for NP-complete problems
The modern information society is enabled by photonic fiber networks characterized by huge coverage and great complexity and ranging in size from transcontinental submarine telecommunication cables to fiber to the home and ...
Nonlinear coupling of relative intensity noise from pump to a fiber ring laser mode-locked with carbon nanotubes
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 ...
