Phys. Rev. Lett. 94, 113903 (2005) [4 pages]Optical Necklace States in Anderson Localized 1D SystemsReceived 8 November 2004; published 22 March 2005 We report on the observation of nonlocalized modes or necklace states of light waves in disordered systems in the Anderson localized regime. The samples consist of positional-disordered binary multilayer systems. Anderson localized modes manifest themselves as narrow high-transmission peaks in the transmission spectrum, whereas the average of the logarithm of the transmission coefficient decreases linearly with thickness. Optical necklace states are observed as modes with a characteristic multiresonance time response and relatively fast decay time. © 2005 The American Physical Society URL:
