Abstract
We present two novel hybrid photonic structures made of silica that possess two well-separated frequency bandgaps. The addition of interstitial air holes in a precise location and size allows these bandgaps to open up with a ratio of ∼ 3 between their central frequencies at the air line ckz/w = 1, thus fulfilling the basic guidance condition for third harmonic generation in hollow-core fibers. In
addition, these designs may serve as high-power laser delivery of two well-separated wavelengths,such as visible and near infrared.
