Sh. Fan et al., GUIDED AND DEFECT MODES IN PERIODIC DIELECTRIC WAVE-GUIDES, Journal of the Optical Society of America. B, Optical physics, 12(7), 1995, pp. 1267-1272
The nature of guided modes and defect modes in periodic dielectric wav
eguides is investigated computationally for model systems in two dimen
sions. It is shown that defect states that exist within the band gap o
f guided modes can be excited to form tightly localized high-Q resonan
ces.
