Microstructured optical fibers (MOFs) with air holes within the structure, such as hole-assisted fibers (HAFs) and holey fibers (HFs), having unique dispersion properties in short-wavelength bands, have captured considerable attention recently thanks to their wide range of practical applications. In particular, supercontinuum (SC) source, which is generated by interplay between many different nonlinear processes occurred in the MOFs, have gathered huge interests both in telecom and nontelecom applications. In this paper, designs and fabrications of HAFs and HFs, having unique dispersion properties in near infrared and visible regime, will be discussed. In particular, we focus on: 1) the dispersion control of HAFs in the 1.0- mum band, which has become of great interest stimulated by maturing ytterbium-doped fiber amplifier (YDFA) technologies, and 2) dispersion shift towards visible wavelengths (500 nm) using HFs. Finally, we will briefly discuss future developments of the MOFs for short-wavelength applications.
