TLDR
In this article, the authors demonstrate experimentally that air-silica microstructure optical fibers can exhibit anomalous dispersion at visible wavelengths, and exploit this feature to generate an optical continuum 550 THz in width, extending from the violet to the infrared.Abstract:
We demonstrate experimentally for what is to our knowledge the first time that air–silica microstructure optical fibers can exhibit anomalous dispersion at visible wavelengths. We exploit this feature to generate an optical continuum 550 THz in width, extending from the violet to the infrared, by propagating pulses of 100-fs duration and kilowatt peak powers through a microstructure fiber near the zero-dispersion wavelength.read more

TL;DR: In this paper, a 300 nm broadband visible continuum has been generated in a 1.8 m length of microstructured fiber pumped at 532 nm by 0.8 ns pulses from a frequency-doubled passively Q-switched Nd:YAG microchip laser.

Generation of a broadband single-mode supercontinuum in a conventional dispersion-shifted fiber by use of a subnanosecond microchip laser.
TL;DR: It is shown by detailed spectral analysis that this supercontinuum originates from a preliminary four-wave mixing process with multimode phase matching and subsequent double-cascade stimulated Raman scattering and is transversely single mode as a result of Raman-induced mode competition.

Simultaneous generation of spectrally distinct third harmonics in a photonic crystal fiber

TL;DR: Frequency-resolved optical gating experiments combined with analysis and modal simulations suggest that the mechanism for the simultaneous generation of two visible radiation components is third-harmonic conversion of the fundamental pulse and its split Raman self-shifted component.

Ultra-low threshold supercontinuum generation in sub-wavelength waveguides.
TL;DR: Using a tapered small-core microstructured fiber with a sub-wavelength diameter core, an octave-spanning supercontinuum with 250 pJ pulses from a femtosecond modelocked Ti:sapphire oscillator is generated.

Endlessly single-mode photonic crystal fiber.
TL;DR: An effective-index model confirms that an all-silica optical fiber made by embedding a central core in a two-dimensional photonic crystal with a micrometer-spaced hexagonal array of air holes can be single mode for any wavelength.
Journal ArticleDOI
Discovery of the soliton self-frequency shift.
TL;DR: The experimental discovery of a continuous shift in the optical frequency of a soliton pulse as it travels down the fiber is described, caused by a Raman self-pumping of the soliton.

Self-phase-modulation in silica optical fibers
Roger H. Stolen,Chinlon Lin +1 more
TL;DR: In this paper, the authors report measurements of frequency broadening due to self-phase modulation (SPM) in optical fibers, using single-mode silica-core fibers and mode-locked argon-laser pulses.
Journal ArticleDOI
Group-velocity dispersion in photonic crystal fibers.
TL;DR: The dispersion properties of photonic crystal fibers are calculated by expression of the modal field as a sum of localized orthogonal functions to derive uniform dispersion values for single mode and double mode fibers.

Slab-coupled waveguides
TL;DR: The slab-coupled waveguide is a multidielectric waveguide that includes such special cases as the single-material fiber, the rib waveguide, and the strip-loaded film guide as mentioned in this paper.
