Microwave photonics with Josephson junction arrays: Negative refraction index and entanglement through disorder

“…Disorder may have a dramatic influence in the transport properties of the photonic crystal. 56 On the one hand, the transmission coefficient averaged over an ensemble of random scatterers T decays exponentially with increasing length L of the disordered media, similar to Anderson's localization. 57 On the other hand disorder fights against the interference phenomena that gives rise to the existence of band gaps.…”

Influence of imperfections on the insulating and guiding properties of finite Si-inverted opal crystals

“…This question is discussed in numerous references addressing models of disorder in 1D-2D lattices [3][4][5][6][7][8] or in full 3D crystal arrangement [9][10][11][12][13][14][15][16][17][18][19]. The former models are applied to planar PhCs and photonic crystal waveguides (PCWs).…”

Influence of residual disorder on the anticrossing of Bloch modes probed inkspace

“…The dispersion curve, which describes the frequency of the wave as a function of its wave vector k, provides a clear insight into all essential propagation phenomena in photonic structures. Recent theoretical studies on photonic waveguides 19,20 have demonstrated that the presence of nanometer scale disorder drastically modifies the ideal dispersion near a band edge.…”
