Programmable and tunable flat-top supercontinuum laser sources via electro-optic intensity and phase modulation scheme

Scientific Reports, 2022
In this study, we presented flat-topped coherent supercontinuum lasers with tunable repetition rates and programmable spectral bandwidths. Supercontinuum sources with ultra-broadband and high-repetition-rate coverage can be achieved by merging ...

Ultraviolet-Extended Supercontinuum Generation in Zero-Dispersion Wavelength Decreasing Photonic Crystal Fibers

IEEE Photonics Journal, 2020
Supercontinuum covering the ultraviolet-blue region is highly useful for fluorescence microscopy. Four zero-dispersion wavelength decreasing photonic crystal fibers with different fiber cross structures and taper profiles are fabricated to extend the ...

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.

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

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 ...

High-power supercontinuum generation with picosecond pulses [PDF]

, 2010
We investigate both theoretically and experimentally the properties of supercontinuum generation in the nearinfrared and visible regimes using high-power picosecond pulses propagating in a photonic crystal optical fiber. We discuss the effect of the pump

Efficient near-infrared supercontinuum generation in tellurite holey fiber pumped 320nm within the normal dispersion regime [PDF]

, 2010
We demonstrate the generation of a 1.1-1.7µm supercontinuum in a 1.3m long air suspended-core tellurite holey-fiber with a nominal zero-dispersion wavelength of ~1.38µm. The fiber is pumped at 1.06µm with a 20ps pulsed fiber laser.
