Visible continuum generation in air–silica microstructure optical fibers with anomalous dispersion at 800 nm
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

Experimental and numerical analysis of widely broadened supercontinuum generation in highly nonlinear dispersion-shifted fiber with a femtosecond pulse
TL;DR: In this article, the authors report the analysis of ultrawideband supercontinuum generation in a highly nonlinear dispersion-shifted fiber, where a >1000-nm-spanning white-light continuum is generated by pumping the femtosecond fiber laser pulse at the extreme vicinity of the zero-dispersion wavelength of the fiber.

Tapered photonic crystal fibers.
TL;DR: This work demonstrates the tapering of a photonic crystal fiber to achieve a microstructure pitch of less than 300 nm and shows that the fundamental gap can be shifted down to the communications wavelengths, or even further to the visible spectrum.

Observation of optical-fibre Kerr nonlinearity at the single-photon level
TL;DR: In this paper, the authors demonstrate the first experimental observation of optical nonlinearity at the single-photon level in an optical fiber and discuss the feasibility of quantum information processing using optical fibres, taking into account the observed Kerr nonlinearities, accompanied by ultrafast response time and low induced loss.

Pulse compression with supercontinuum generation in microstructure fibers
TL;DR: In this paper, the authors demonstrate the generation of 5.5-fps pulses by dispersive compression of a supercontinuum generated with 15-fs pulses from a Ti:sapphire laser in a 5mm-long microstructure fiber.

High average power supercontinuum generation in photonic crystal fibers
TL;DR: In this article, the femto and picosecond pulses delivered by the amplifier are coupled into two different photonic crystal fibers and obtained the highest output power of 5 W with a spectrum ranging from below 500 nm up to above 1800 nm.

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.
