Beggs, D.M. and Kaliteevski, M.A. and Abram, R.A. and Cassagne, D. and Albert, J.P. (2005) 'Disorder-induced modification of the transmission of light through two-dimensional photonic crystals.', Journal of physics : condensed matter., 17 (12). pp. 1781-1790.
Disordered two-dimensional photonic crystals with a complete photonic band-gap have been investigated. Transmission and reflection spectra have been modelled for both ballistic and scattered light. The density of states and electromagnetic field profiles of disorder-induced localized states have also been calculated, for various levels of disorder. It is found that there is a threshold-like behaviour in the amount of disorder. Below the threshold, it is seen that there is a vanishing probability of disorder-induced localized states being introduced into the centre of the photonic band-gap, but that edge-states narrow the band-gap. Above the threshold, there is a non-zero probability of disorder-induced localized states throughout the photonic band-gap, and the modification of the transmission and reflection spectra due to disorder rapidly increases with increasing disorder.
