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

Phase-locked white-light continuum pulses: toward a universal optical frequency-comb synthesizer
Marco Bellini,Theodor W. Hänsch +1 more
TL;DR: It is demonstrated that two white-light continuum pulses that are independently generated by phase-locked ultrashort laser pulses are locked in phase and show surprisingly clear and stable Young interference fringes and suggests that such white- light continuum pulses can be used to realize a broad frequency comb for absolute frequency measurements from the IR to the UV.

Continuous-wave, high-power, Raman continuum generation in holey fibers.
TL;DR: The possibility of using low pump power for cw Raman continuum generation is demonstrated by optimization of the pump peak power and by accounting for the loss-related reduction of the effective length of Raman interaction in holey fibers.

Carrier-envelope phase-controlled quantum interference of injected photocurrents in semiconductors
TL;DR: It is demonstrated that quantum interference control of injected photocurrents in a semiconductor using the phase stabilized pulse train from a mode-locked Ti:sapphire laser results in a signal-to-noise ratio of 40 dB, enabling solid-state detection of carrier-envelope phase shifts of a Ti:Sapphire oscillator.

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.
