In this paper, we report a numerical study of the supercoin (SC) generation in solid-core photonic crystal fibers infiltrated with water-ethanol mixtures. A photonic crystal fiber is constructed as borosilicate glass NC21, which consists of 7 rings of air holes infiltrated with water-ethanol mixture[r]

One of the appealing features of photonic crystals has become a possibility to alter the dispersion of electromagnetic waves (Soukoulis, 1996) so that in a certain spectral region vg becomes significantly smaller than the speed of light in vacuum. This “slowlight” effect (Milonni, 2005) attra[r]

On the other hand, the selective infiltration of few holes can provide an alternative approach for integrated[r]
