    Using a focused beam from an argon-ion laser, porous silicon is partially oxidized, creating lateral confinement for a buried waveguide. In practice, the full oxidation shown does not take place because there is insufficient oxygen beneath the surface—the material collapses instead. Even so, partial oxidation is still enough to create an efficient waveguide.
    Researchers at the Istituto Elettrotecnico Nazionale Galileo Ferraris (IEN; Turin, Italy) have fabricated and patterned porous silicon to provide lateral waveguide confinement...

    Ytterbium-doped holey fiber pumped with 966-nm light compresses and amplifies chirped 1.06-µm seed pulses. When in the holey fiber, the seed pulses quickly form solitons whose wavelength depends on the amount of amplifier gain. Wavelength tuning range of the setup is 1.06 to 1.33 µm. At higher pump powers, multicolor pulses are produced, some with wavelengths up to 1.58 µm. The solid core of the fiber, which carries the solitons, is approximately 2 µm in diameter.
    Conventional wavelength-tunable sources of femtosecond light pulses in the 1 to 1.3-µm range typically consist of large solid-state lasers with complex, high-precision cavities...
