Webposition and width of the photonic band gap depend on the nanowire diameter for a given periodicity17 and thus under-score the importance of the simulations in designing hybrid nanowire/photonic crystal structures that are coupled. The effect of the photonic band gap on the nanowire photonic crystal hybrid structures was first investigated by ... WebDec 1, 2024 · The results show that the band gap of the three-wings defect photonic crystal changes little in a wavy shape, which fluctuates around 3.55 × 10 −2 (ɷ a /2πc). When the rotation angle is 46°, the maximum band gap is about 3.641 × 10 −2 (ɷ a /2πc), and its TM band structure is shown in Fig. 3 (b).

WebFeb 1, 2011 · The dispersion, which expresses the variation with wavelength of the guided-mode group velocity, is one of the most important properties of optical fibers. Photonic crystal fibers (PCFs) offer much larger flexibility than conventional fibers with respect to tailoring of the dispersion curve. This is partly due to the large refractive-index contrast … WebApr 4, 2002 · Abstract.
