Broadband Continuous Spectral Control of a Single Wavelength Polymer-Based Solid-State Random Laser
Bhupesh Kumar, Sebastian Schulz, Patrick Sebbah
We demonstrate temperature-controlled spectral tunability of a partially-pumped single-wavelength random laser in a solid-state random laser based on DCM (4-dicyanomethylene-2-meth…
2D tunable all-solid-state random laser in the visible
Bhupesh Kumar, Ran Homri, Patrick Sebbah
A two-dimensional (2D) solid-state random laser emitting in the visible is demonstrated, in which optical feedback is provided by a controlled disordered arrangement of air-holes i…
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…
Fatigueless response of spider draglines in cyclic torsion facilitated by reversible molecular deformation
Bhupesh Kumar, Kamal P. Singh
We demonstrate that spider draglines exhibit a fatigueless response in extreme cyclic torsion up to its breaking limit. The well defined Raman bands at and sh…
