Discrepant transport characteristics under Anderson localization at the two limits of disorder
Randhir Kumar, Sandip Mondal, M. Balasubrahmaniyam +2
Anderson localization is a striking phenomenon wherein transport of light is arrested due to the formation of disorder-induced resonances. Hitherto, Anderson localization has been…
Collective Rayleigh Scattering from Molecular Ensembles under Strong Coupling
Adina Golombek, Mukundakumar Balasubrahmaniyam, Maria Kaeek +2
Rayleigh scattering is usually considered to be the elastic scattering of photons from sub-wavelength physical objects, such as small particles or molecules. Here, we present the s…
Direct experimental determination of critical disorder in one-dimensional weakly disordered photonic crystals
M. Balasubrahmaniyam, Sushil Mujumdar
We report experimental measurement of critical disorder in weakly disordered, one-dimensional photonic crystals. We measure the configurationally-averaged transmission at various d…
Anderson localization at the hybridisation gap in a plasmonic system
M. Balasubrahmaniyam, Ajay Nahata, Sushil Mujumdar
Disorder-induced Anderson localization in quasiparticle transport is a challenging problem to address, even more so in the presence of dissipation as the symptoms of disorder-induc…
Temporal complexity in emission from Anderson localized lasers
Randhir Kumar, M. Balasubrahmaniyam, K Shadak Alee +1
Anderson localization lasers exploit resonant cavities formed due to structural disorder. The inherent randomness in the structure of these cavities realizes a probability distribu…
