Oscillating propagation and parametric instability of the partial Gaussian beam in graded-index multimode fibers

Frontiers in Physics, 2022
We investigate the input and propagation characteristics and geometric parametric instability of the partial Gaussian beam limited by the fiber face area in a graded-index multimode fiber.

Hydrodynamic Supercontinuum

Physical Review Letters, 2013
We report the experimental observation of multi-bound-soliton solutions of the nonlinear Schrodinger equation (NLS) in the context of hydrodynamic surface gravity waves. Higher-order N-soliton solutions with N = 2, 3 are studied in detail and shown to be associated with self-focusing in the wave group dynamics and the generation of a steep localized ...

Over-Two-Octave Supercontinuum Generation of Light-Carrying Orbital Angular Momentum in Germania-Doped Ring-Core Fiber

Sensors, 2022
In this paper, we design a silica-cladded Germania-doped ring-core fiber (RCF) that supports orbital angular momentum (OAM) modes. By optimizing the fiber structure parameters, the RCF possesses a near-zero flat dispersion with a total variation of

1.6-Octave Coherent OAM Supercontinuum Generation in As₂S₃ Photonic Crystal Fiber

IEEE Access, 2020
We design and simulate an all-normal dispersion arsenic trisulfide (As2S3) photonic crystal fiber (PCF) with high nonlinearity to enable a flat and coherent orbital angular momentum (OAM) supercontinuum (SC) generation.

Active Supercontinuum Injection for Optical Parametric Chirped Pulse Amplification

IEEE Photonics Journal, 2017
The anticipant supercontinuum is a prerequisite for the pump seed generation in an optical parametric chirped pulse amplification (OPCPA) system. To achieve the anticipant supercontinuum, we develop an active method operated in a two-level control scheme

Mid-Infrared Supercontinuum and Frequency Comb Generations by Different Optical Modes in a Multimode Chalcogenide Strip Waveguide

IEEE Access, 2020
Supercontinuum (SC) with broad bandwidth and high coherence is crucial in the SC-based frequency comb source generation. In this paper, we numerically investigate the mid-infrared (MIR) SC generations with the three optical modes (TE00, TE10, and TE20 ...
