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

Process for fabricating tapered microstructured fiber system and resultant system
Juhi Chandalia,David John Montclair Di Giovanni,Benjamin J. Eggleton,Sandra Greenberg Murray Hill Kosinski,Robert S. Windeler +4 more
TL;DR: In this paper, a microstructured fiber has a core region, a cladding region, and one or more axially oriented elements (e.g., capillary air holes) in the cladding regions.

Mode-locked laser pulse trains with subfemtosecond timing jitter synchronized to an optical reference oscillator
TL;DR: This method takes advantage of the tremendous leverage that is possible when stability is transferred from the optical to the microwave domain, and independently phase lock the repetition rates of two femtosecond lasers at their approximately 456, 000th harmonic to a common optical oscillator.

TL;DR: In this paper, a particular design of a highly birefringent PCF with attractive features for pressure sensing applications was investigated, which exhibits a low and positive temperature sensitivity (KT < 0.1 rad/(K⋅m)), and relatively high and negative mechanical (pressure) sensitivity (Kp ≤ −10 rad/(MPa⋆m)), which supports its possible use as a mechanical sensor that does not require any temperature compensation.

Midinfrared supercontinuum generation via As2Se3 chalcogenide photonic crystal fibers.
TL;DR: Using numerical analysis, the results of optofluidic and rod filling techniques for the broadening of supercontinuum spectra generated by As2Se3 chalcogenide photonic crystal fibers (PCFs) show an ultra-flattened near-zero dispersion and a ripple-free spectral broadening as wide as 3.86 μm.

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.

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.

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.

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.
