The design of an SC lightwave source is described that uses a scaling rule among the parameters in an SC generating fiber and a seed optical pulse. Finally, recent efforts to apply SC lightwave source to optical network systems are mentioned.展开更多

A taper tower is used to modify the structures of the fiber preform, and four steps of fiber fabrication and different structures of fiber samples are given. The mode structures and beating characteristics of a photonic crystal fiber sample with two successive cores are investigated in detail with the help of a supercontinuum light source, a charge-coupled device （CCD） camera, and an optical spectrum analyzer. The test results show a clear beating phenomenon between two orthotropic polarization modes with a 2.8-nm peak interval in wavelength.展开更多
