Impact of Non-Hermiticity and Nonlinear Interactions on Disordered-Induced Localized Modes
Bhupesh Kumar, Patrick Sebbah
If disorder-induced Anderson localized states have been observed experimentally in optics, their study remains challenging leaving a number of open questions unsolved. Among them,…

Localized modes revealed in Random Lasers
Bhupesh Kumar, Ran Homri, Priyanka Priyanka +3
In sufficiently strong scattering media, light transport is suppressed and modes are exponentially localized. Anderson-like localized states have long been recognized as potential…

Selective Pumping of Localized States in a Disordered Active Medium
Bhupesh Kumar, Melanie Lebental, Patrick Sebbah
Light scattering and localization in strongly scattering disordered systems is governed by the nature of the underlying eigenmodes, specially their spatial extension within the sys…
