Minimizing AMDs in unidirectional WDM rings with grooming factor 6，徐允庆，常彦勋，In wavelength division multiplexing for unidirectional rings,
traffic grooming is used to pack low rate signals into higher rate
streams to share a wavelength. The grooming
The influence on photonic crystal fiber dispersion of the size of air holes in different rings within the cladding is investigated using a semivectorial finite difference method. Numerical results reveal that the photonic crystal fiber dispersion is
