TL;DR: More than 1000 optical frequency channels were generated with 12.5 GHz spacing from a single supercontinuum source in this article, and 600-700 channels for the wavelength range 1512-1580 nm were confirmed to offer SNRs and Q factors sufficient for multi-span 2.5 Gbit/s DWDM transmission.

TL;DR: In this paper, a supercontinuum WDM source is successfully transmitted over a 40 km dispersion-shifted fiber using a 400 GHz channel-spaced arrayed-waveguide grating WDM MUX/DEMUX as well as a 100 Gbit/s-10 Gbps all-optical TDM all-over-the-place (TDM-DEMUX) source.

TL;DR: This work demonstrates continuous wave supercontinuum generation extending to the visible spectral region by pumping photonic crystal fibers at 1.07 microm with a 400 W single mode, continuous wave, ytterbium fiber laser.
Abstract: We demonstrate continuous wave supercontinuum generation extending to the visible spectral region by pumping photonic crystal fibers at 1.07 microm with a 400 W single mode, continuous wave, ytterbium fiber laser. The continuum spans over 1300 nm with average powers up to 50 W and spectral power densities over 50 mW/nm. Numerical modeling and understanding of the physical mechanisms has led us to identify the dominant contribution to the short wavelength extension to be trapping and scattering of dispersive waves by high energy solitons.

TL;DR: The wave number matching conditions for the generation of new spectral components in optical fibers pumped with a solitonic pulse and a weak continuous wave are derived and an analytical method of finding the amplitudes of the generated waves is presented.
Abstract: We develop a theory of the generation of new spectral components in optical fibers pumped with a solitonic pulse and a weak continuous wave (cw). We derive the wave number matching conditions for the above process and present an analytical method of finding the amplitudes of the generated waves. We discuss related effects of the depletion of the cw pump and spectral recoil on the soliton. We also point out examples of the generation of supercontinuum spectra in fibers, where mixing between solitons and dispersive waves plays an important role.

TL;DR: The spectral broadening of ~1 μJ 30 fs pulses propagating in an Ar-filled hollow-core photonic crystal fiber results in efficient emission of dispersive waves in the deep-UV region.
Abstract: We report on the spectral broadening of ~1 μJ 30 fs pulses propagating in an Ar-filled hollow-core photonic crystal fiber. In contrast with supercontinuum generation in a solid-core photonic crystal fiber, the absence of Raman and unique pressure-controlled dispersion results in efficient emission of dispersive waves in the deep-UV region. The UV light emerges in the single-lobed fundamental mode and is tunable from 200 to 320 nm by varying the pulse energy and gas pressure. The setup is extremely simple, involving <1 m of a gas-filled photonic crystal fiber, and the UV signal is stable and bright, with experimental IR to deep-UV conversion efficiencies as high as 8%. The source is of immediate interest in applications demanding high spatial coherence, such as laser lithography or confocal microscopy.
