Abstract
The comparison of two types of photonic crystal fiber coupler (PCFC) based on LMA8 and LMA10 fibers are presented in this paper. The couplers preparation process based on biconical fiber technique without air-holes collapsing. The same parameters of elongation process have given slightly different results. The LMA10-PCFC has stronger polarization dependence and many points with 50x50 coupling ratio in range 800 - 1600nm. The LMA8-PCFC has less polarization sensitivity and better spectral characteristic in range 1500 - 1600nm as well as lower losses. It is observed that 50x50 coupling regions appear in second and third telecommunication windows.
