Design of microstructure optical fibers as broadband dispersion compensators

This paper presents a numerical design of a high negative dispersion microstructure optical fiber for dispersion compensation in a wide range of wavelengths. The finite-element method with perfectly matched absorbing layers boundary condition is used to investigate the guiding properties. The designed novel dispersion compensating fiber (DC-MOF) shows that it is possible to obtain a larger negative dispersion coefficient, better dispersion slope compensation, and lower confinement losses in the entire telecommunication (1400–1600 nm) band by using a modest number of design parameters and very simple cladding design.
