Magnetooptic effect of photonic crystal fiber in blue region of visible spectrum

摘要

The phenomenon of optical birefringence in optical fibers is caused by external factors and stress induced by the manufacturing process. This optical birefringence makes it difficult to apply optical fibers as a polarimetric sensors head. Author of this paper, proposes the application of index guiding photonic crystal fibers because stress values in a fiber core caused by internal and external factors are lower. In this paper investigation results extended in comparison with the previous author's investigations are presented. This extension relies on investigation of magnetooptic for wavelength 405 nm. On the basis of experimental results optimal work points of optical sensing fibers were determined.
