Photon diffusion in space and time in a second-order nonlinear disordered medium
Rabisankar Samanta, Romain Pierrat, Rémi Carminati +1
We report experimental and theoretical investigations on photon diffusion in a second-order nonlinear disordered medium under conditions of strong nonlinearity. Experimentally, pho…
Quantum echo route towards exceptional points in Anderson localized lasers
Krishna Joshi, Sushil Mujumdar
Exceptional points, that are spectral degeneracies in the parameter space of non-Hermitian systems, have evoked a massive interest in the optical domain owing to their striking con…
Anomalous transport regime in non-Hermitian, Anderson-localizing hybrid systems
Himadri Sahoo, R Vijay, Sushil Mujumdar
In a disordered environment, the probability of transmission of a wave reduces with increasing disorder, the ultimate limit of which is the near-zero transmission due to Anderson l…
Speckle decorrelation in fundamental and second-harmonic light scattered from nonlinear disorder
Rabisankar Samanta, Romain Pierrat, Rémi Carminati +1
Speckle patterns generated in a disordered medium carry a lot of information despite the apparent complete randomness in the intensity pattern. When the medium possesses …
Optical Thouless conductance and level-spacing statistics in two-dimensional Anderson localizing systems
Sandip Mondal, Randhir Kumar, Martin Kamp +1
We experimentally investigate spectral statistics in Anderson localization in two-dimensional amorphous disordered media. Intensity distributions captured over an ultrabroad wavele…
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…
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…
Imaging in turbid media using quasi-ballistic photons
Venkatesh Gopal, Sushil Mujumdar, Hema Ramachandran +1
We study by means of experiments and Monte Carlo simulations, the scattering of light in random media, to determine the distance upto which photons travel along almost undeviated p…
