Selective amplification of scars in a chaotic optical fiber
Claire Michel, Valérie Doya, Olivier Legrand +1
In this letter we propose an original mechanism to select scar modes through coherent gain amplification in a multimode D-shaped fiber. More precisely, we numerically demonstrate h…
Localized Modes in a Finite-Size Open Disordered Microwave Cavity
David Laurent, Olivier Legrand, Patrick Sebbah +2
We present measurements of the spatial intensity distribution of localized modes in a two-dimensional open microwave cavity randomly filled with cylindrical dielectric scatterers.…
Optical Scar in a chaotic fibre
Valérie Doya, Olivier Legrand, Claire Michel +1
We propose to use a multimode optical fiber with a D-shaped cross section as a privileged system to image wavefunctions of a chaotic system. Scar modes are in particular the sub je…
Complete S-matrix in a microwave cavity at room temperature
Jerome Barthelemy, Olivier Legrand, Fabrice Mortessagne
We experimentally study the widths of resonances in a two-dimensional microwave cavity at room temperature. By developing a model for the coupling antennas, we are able to discrimi…
Boundary losses and spatial statistics of complex modes in a chaotic microwave cavity
Jerome Barthelemy, Olivier Legrand, Fabrice Mortessagne
We experimentally study the various manifestations of ohmic losses in a two-dimensional microwave chaotic cavity and exhibit two different contributions to the resonance widths. We…
