HAFs and HFs (MOFs) having unique dispersion properties in near infrared and visible regime will be discussed. In particular, we focus on the dispersion control in a 1.0μm band which have gathered rapidly increasing interests for the aspects of both telecom and non-telecom applications. Furthermore, dispersion shift towards visible wavelengths using a holey fiber technology has tried and the results will be explained. Finally, we will briefly discuss about the potential usage of the MOFs for short wavelength transmission.© (2007) COPYRIGHT SPIE--The International Society for Optical Engineering.
