Topological Modes in One Dimensional Solids and Photonic Crystals
Timothy J. Atherton, Celia A. M. Butler, Melita C. Taylor +4
It is shown theoretically that a one-dimensional crystal with time reversal symmetry is characterized by a Z_{2} topological invariant that predicts the existence or otherwise of e…

Transmutation of singularities and zeros in graded index optical instruments: a methodology for designing practical devices
I. R. Hooper, T. G. Philbin
We describe a design methodology for modifying the refractive index profile of graded-index optical instruments that incorporate singularities or zeros in their refractive index. T…
