Resolved Anderson localization of light in dense three-dimensional dielectric disorder
Yevgen Grynko, Jens Förstner
Strong localization of light in 3D dielectric disorder is challenging to establish because localized contributions can be hidden by diffusive leakage and finite-sample loss. We per…

3D Anderson localization of light in disordered systems of dielectric particles
Yevgen Grynko, Dustin Siebert, Jan Sperling +1
We investigate light transport in three-dimensional disordered media composed of irregular dielectric particles using large scale full-wave simulations. For subwavelength particles…

Gain-induced spectral non-degeneracy in type-II parametric down-conversion
Behnood Taheri, Denis Kopylov, Manfred Hammer +3
We demonstrate the novel effect of gain-induced spectral shifts in the type-II parametric down-conversion (PDC) process, which results in a transition from degenerate to non-degene…
