【Abstract】 Photonic crystal fibers (PCFs) can have large negative dispersion by designing a reasonable geometric structure, and this fantastic feature can be used to fabricate a novel kind of dispersion compensation fiber (DCF) device for compensating the positive dispersion of the regular transmission fibers widely used in modern communication systems. This new PCF-DCF may be much shorter than newly developed DCF whose minus dispersion is only several hundreds times of the transmission fibers. In this paper, the DCF-application potential of the PCFs in the modern optical communication system is demonstrated, along with the designing method of the PCF’s configuration for compensating the dispersion of the transmission fibers.更多还原
