We present a holey fiber (HF) with elliptical air-holes located in the center core area that ensures high birefringence, near-zero ultra-flattened chromatic dispersion and very low confinement losses in a wide wavelength range. The finite element met

Two square photonic crystal fibers (SPCFs), one made of silica (SiO2) and the other made of high index lead silicate soft glass (SF57), are numerically analyzed, compared, and proposed in this paper. Both designs of SPCFs show very high negative and

A dispersion-compensating square-lattice photonic crystal fiber for broadband compensation which covers the S, C and L communication bands, i.e. wavelength ranging from 1 460 nm to 1 625 nm is proposed in this paper. Theoretically, it is shown a nega
