We report a novel idea for achieving highly efficient dispersion-compensating Bragg fiber by exploiting a modified quarter-wave stack condition. Our Bragg fiber yielded an average dispersion of approximately -1800 ps/(nm km) across the C band for the fundamental TE mode and an ultrahigh figure of merit of approximately 180,000 ps/(nm dB), which is at least 2 orders of magnitude higher than that of conventional dispersion-compensating fibers. The proposed methodology could be adopted for the design of a dispersion compensator across any desired wavelength range.
我们报告了一种通过利用改进的四分之一波长堆叠条件来实现高效色散补偿布拉格光纤的新想法。我们的布拉格光纤在C波段上，对于基模TE模式产生了约-1800 ps/(nm·km)的平均色散以及约180,000 ps/(nm·dB)的超高品质因数，这比传统色散补偿光纤至少高两个数量级。所提出的方法可用于设计任何所需波长范围内的色散补偿器。
