Paper Abstract

A highly birefringent dispersion compensating microstructure optical fiber (MOF) based on a modified spiral (MS)-MOF is presented that successfully compensates the dispersion covering the E- to L-communication bands ranging from 1370 to 1640 nm. It is shown theoretically that it can obtain a negative dispersion coefficient of about −221 to −424  ps/(nm⋅km) ) over S to L bands and −327  ps/(nm⋅ km) ) at the operating wavelength of 1550 nm. The relative dispersion slope is perfectly matched to that of single-mode fiber of about 0.0036  nm −1 . Besides, the proposed MS-MOF offers high birefringence of 1.79×10 −2 with a large nonlinear coefficient of about 41.8  W −1  km −1 at the operating wavelength along with two zero dispersion wavelengths at 610 and 1220 nm. Futhermore, the variation of structural parameters is also studied to evaluate the tolerance of the fabrication.
