We derive a pulse propagation equation for a graphene-clad optical fiber, treating the optical response of the graphene and nonlinearity of the dielectric fiber core as perturbations in asymptotic expansion of Maxwell equations. We analyze the effective nonlinear and attenuation coefficients due to the graphene layer. Based on the recent experimental measurements of the nonlinear graphene condu...

We have given designs of a small dispersion fiber with large effective area and small dispersion slope. The fiber has flat modal field over the central part of the core, which provides large mode field diameter (8.3 um at Λ0 = 1550 nm) leading to the relatively large effective area (Aeff = 56.1 um ) required to reduce nonlinear effects. The total dispersion of the proposed fiber is in the range...

Massive fiber-to-the-home network deployment requires never ending equipment upgrades operating at higher bandwidth. We show effective signal slicing method, which can reuse low bandwidth opto-electronical components for optical communications at higher bit rates.

A novel very-large-mode-area asymmetric rod-type fiber was fabricated and experimentally characterized. The fiber supports effective and robust single-mode operation for a core diameter of 66μm making it attractive for high power amplifier systems.
