Single-wall carbon nanotubes and graphene oxide-based saturable absorbers for low phase noise mode-locked fiber lasers
Low phase noise mode-locked fiber laser finds important applications in telecommunication, ultrafast sciences, material science, and biology, etc. In this paper, two types of carbon nano-materials, i.e. single-wall carbon ...
Low-timing-jitter mode-locked fiber laser based on graphene oxide pva thin film as saturable absorber
We demonstrate a mode-locked fiber laser based on graphene oxide saturable absorber at 1550nm. The laser has a timing jitter of 53fs (100Hz to 100kHz). The contribution from the slow saturable absorber is also investigated.
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 ...
