We propose a novel type of photonic crystal fiber with low fattened dispersion and high nonlinearity for four wave mixing. The dispersion and nonlinearity coefficient are investigated simultaneously by using the full vectorial finite element method with anisotropic perfectly matched layers. The optimized result has been obtained by adjusting the design parameter of the proposed fiber, which has dispersion is -1.53 ps•nm−1 km−1 at wavelength of 1.55μm, and in addition the relatively small effective mode area of 2.23μm2 is obtained at the same wavelength, which will induce higher nonlinearity coefficient is close 54.8 W-1• km-1 at the wavelength of 1.55μm. The proposed PCF is suitable for applications as a chromatic dispersion controller, dispersion compensator, or as candidate for the nonlinear optical systems because of its small effective mode area.

Abstract In this paper, the capabilities of chromatic dispersion compensation of a photonic crystal fiber with a hexagonal distribution of circular air holes was investigated. The vector finite element method with scattering boundary condition was used to analyze a set of configurations of the fiber in which the distance between air holes’ centers was modified. With this method it was possible to obtain the values of chromatic dispersion and confinement factor in the C fiber band. The best suited configurations were tested in a 160 km optical link with a bit rate of 40 Gbps. The performance was evaluated by measuring the bit error rate for a set of 20 channels with channel spacing of 100 GHz. The simulation results showed that is possible to reach values of chromatic dispersion as low as $- 850{{{\rm{ps}}} \over {{\rm{nm}} \middot {\rm{km}}}}$ , confinement losses close to 10−3 dB/km and good BER results in the order of 10−17 for a wavelength of 1550 nm.

AbstractGraphene has been widely used in silicon-based optical modulators for its ultra-broadband light absorption and ultrafast optoelectronic response. By incorporating graphene and slow-light silicon photonic crystal waveguide (PhCW), here we propose and experimentally demonstrate a unique double-layer graphene electro-absorption modulator in telecommunication applications. The modulator exhibits a modulation depth of 0.5 dB/μm with a bandwidth of 13.6 GHz, while graphene coverage length is only 1.2 μm in simulations. We also fabricated the graphene modulator on silicon platform, and the device achieved a modulation bandwidth at 12 GHz. The proposed graphene-PhCW modulator may have potentials in the applications of on-chip interconnections.
