However, the localization is in the order of half wavelength Due to the diffraction-limited-based mechanism in photonic bandgap formation. In this paper, the possibility of sub-wavelength confinement of light in a photonic crystal waveguide is examined by ionic materials elements. It is shown that light can be confined in an area smaller than one Two-hundredth of the square wavelength of the waveguide modal field. %> http://opsi.ir/article-1-759-en.pdf %P 817-820 %& 817 %! %9 Research %L A-10-1-739 %+ Shahid Beheshti University %G eng %@ 1126-3278 %[ 2015
