An Improved Non-linear Nearly-zero Dispersion Flattened Photonic Crystal Fiber with the Threefold Symmetry Core

Popis výsledku v původním jazyce

A new type of dispersion flattened photonic fiber is presented. The fiber has an improved threefold symmetry core that consists of a silica core surrounded by three low-index regions and three air-holes. It can be observed from numerical simulation employing the full-vectorial finite difference frequency domain method that nearly-zero ultra-flattened dispersion can be obtained over the wavelength range of 1250-1700 nm. All fiber's parameters are found to be non immune to imperfections of geometry. An attention should though be paid to the potential fabrication process. The chromatic dispersion behavior with fabrication tolerances of 1 % and 2 % has been numerically demonstrated. Finally, fiber designs with five different hole-to-hole spacing (pitch) have been proposed. Each of the proposed fibers exhibits remarkable chromatic dispersion properties, such as nearly-zero ultra-flattened dispersion over wide wavelength range or zero dispersion at the wavelength of 1550 nm.
