  • Abstract
    We have systematically studied Bragg-grating filters in Si photonic-wire waveguides. We found an abnormal localized optical mode on the numerical calculations and verified it on the experimental measurements. This phenomenon originates from high index-contrast between the waveguide materials. Zero photonic band-gap structure was experimentally realized at transition structure of abnormal localized optical mode in 1-D photonic crystal.
