Dispersion Compensating Square Photonic Crystal Fiber for Optical Communication Systems

抄録

In this paper, we propose a dispersion compensating square-lattice PCF (SPCF) with high negative dispersion characteristics, low confinement losses and relative dispersion slope closely matching the one of conventional single mode fiber (SMF). The design of six air-hole rings SPCF with dispersion coefficient of about -280∼ -390 ps/(nm·km) and low confinement loss of less than 10^-4 dB/km within a considered wavelength range, is confirmed by numerical simulations. In addition, we discuss the splicing problem, its solution and influence of design parameters within a tolerance of ±1% on the proposed SPCF's transmission properties.
