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…
Subwavelength pulse focusing and perfect absorption in the Maxwell fisheye
Gautier Lefebvre, Marc Dubois, Younes Achaoui +4
Maxwell's fisheye is a paradigm for an absolute optical instrument with a refractive index deduced from the stereographic projection of a sphere on a plane. We investigate experime…
Hyperuniform disordered parametric loudspeaker array
Kun Tang, Yuqi Wang, Shaobo Wang +7
A steerable parametric loudspeaker array is known for its directivity and narrow beam width. However, it often suffers from the grating lobes due to periodic array distributions. H…
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…
Dynamic cloaking of a diamond-shaped hole in elastic plate
Kun Tang, Eitam Luz, David Amram +3
Invisibility cloaks for flexural waves have been mostly examined in the continuous-wave regime, while invisibility is likely to deteriorate for short pulses. Here, we propose the p…
