Directional supercontinuum generation

Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF), 2018
Directional supercontinuum is generated in a silicon-rich nitride waveguide with two zero dispersion wavelengths. The supercontinuum is caused by interaction between a soliton and a pulse in the normal dispersion regime leading to dispersive waves.

Tailored Soliton Statistics in Supercontinuum Generation

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
Supercontinuum (SC) generation in highly nonlinear photonic crystal fibers (PCF) has stimulated tremendous interest in recent years [1]. Particular results that have received recent widespread attention concern the observation of “optical rogue waves,” statistically rare extreme red-shifted Raman solitons appearing on the long wavelength edge of the SC

Supercontinuum generated by six-photon mixing

Optics Letters, 1988
We obtain the shape, phase, and spectral distribution of an ultrafast pulse propagating in a chi((5)) medium (six-photon mixing). The calculation is performed in the plane-wave approximation for a dispersionless medium but with self-steepening present.

Extreme supercontinuum generation to the deep-UV

2011 International Quantum Electronics Conference (IQEC) and Conference on Lasers and Electro-Optics (CLEO) Pacific Rim incorporating the Australasian Conference on Optics, Lasers and Spectroscopy and the Australian Conference on Optical Fibre Technology, 2011
Pumping a sharply tapered (5–30 mm taper lengths) solid-core photonic crystal fiber with 130 fs, 2 nJ pulses at 800 nm generates an efficient supercontinuum down to a record-breaking 280 nm in the deep-UV.

Supercontinuum generation in ultraviolet-irradiated fibers

Optics Letters, 2004
We demonstrate that UV exposure of highly nonlinear, germanosilicate fibers causes a strong change in their chromatic dispersion and can significantly alter the infrared supercontinuum generation in these fibers. By varying the level of UV exposure to the fiber, we show that the dispersion zero and the short-wavelength edge of the supercontinuum can be

In-amplifier mid-infrared supercontinuum generation

Optics Letters, 2015
Mid-infrared supercontinuum (SC) generation from 2.6 to 4.1 μm is demonstrated in a single-mode erbium-doped fluoride glass fiber amplifier pumped at 976 nm and seeded by an optical parametric generation (OPG) source emitting 400 ps pulses at 2.75 μm. Up to 82% of the SC power is generated beyond 3 μm.

Extreme supercontinuum generation to the deep UV

Optics Letters, 2012
We report the formation of an ultrabroad supercontinuum down to 280 nm in the deep UV by pumping sharply tapered (5-30 mm taper lengths) solid-core photonic crystal fibers with 130 fs, 2 nJ pulses at 800 nm. The taper moves the point of soliton fission to a position where the core is narrower, a process that requires normal dispersion at the input face

Supercontinuum generation and its applications

SPIE Proceedings, 2005
In this paper, we describe the design theory for the supercontinuum spectrum generation in an optical fiber. To generate a wideband supercontinuum spectrum, the balance between fiber nonlinearity and the amount of group velocity dispersion is important. Secondly, the experimental results of supercontinuum generation are shown.

Supercontinuum Generation in Optical Fibers

2010
The optical fiber based supercontinuum source has recently become a significant scientific and commercial success, with applications ranging from frequency comb production to advanced medical imaging. This one-of-a-kind book explains the theory of fiber supercontinuum broadening, describes the diverse operational regimes and indicates principal areas ...

Generation of White Light Supercontinuum

2015
Supercontinuum generation (SCG) is a process, where laser pulses with narrow spectral bandwidth (quasi-monochromatic) are converted to pulses with very broad spectral bandwidth.
