Dispersion Analysis Of The Microstructured Fiber

In this paper, the dispersion properties of a squre-lattice varying microstructured optical fiber were caculated using the Compact 2D FDTD method. Obtained results were compared with that of squre-lattice no-varying and triangle-lattice varying microstructured optical fiber. This work has some value to the design and application of the microstructured optical fiber.This paper's main content is shown below :1. The general situation and the calculating methods of the microstructured optical fiber were summarized.2. The basic theory, numerical value stability condition, absorbing boundary condition, and the validation of the Compact 2D FDTD method were introduced.3. The dispertion properties of a squre-lattice varying microstructured optical fiber were calculated, and obtained results were compared with that of squre-lattice no-varying and triangle-lattice varying microstructured optical fiber.
