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…
Diffraction limit of light in curved space
Jingxuan Zhang, Chenni Xu, Patrick Sebbah +1
Overcoming diffraction limit is crucial for obtaining high-resolution image and observing fine microstructure. With this conventional difficulty still puzzling us and the prosperou…
Tracking nanoscale perturbation in active disordered media
Renu Yadav, Patrick Sebbah, Maruthi M. Brundavanam +1
The disorder induced feedback makes random lasers very susceptible to any changes in the scattering medium. The sensitivity of the lasing modes to perturbations in the disordered s…
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…
