Abstract
In this paper, the so-called guided
resonances found in photonic crystal slabs were also obtained theoretically
in periodic dielectric waveguides. And the effectiveness of transmission and
the loss of this system were studied. These guided resonance modes based on
resonance transmission still possess good ability to carry energy through
sharp bends, which will reduce the transmission loss of bends in periodic
dielectric waveguides. Because of the band folding effect, the phase velocity
of the guided mode is larger than the speed of light in the vacuum. These
modes give us a Cerenkov-liked radiation pattern.
