Abstract
:For the study of the dispersion and coupling characteristics of hybrid dua-l core Photonic Crystal Fibers (PCF),we
propose a new type of hybrid dua-l core PCF based on two light guiding mechanisms:total internal reflection and photonic band-
gap the basis of the coupled-mode theory,we analyze its effective index,coupling length and dispersion characteris-
tics by using the finite element method and the plane wave expansion method,and study the directional couplers and optical
wavelength simulation results show that the proposed PCF has large negative dispersion and fine coupling prop-
results have significant reference values for the theoretical research on the coupling and sensing properties of dua-l
core PCF and the practi
