Black hole optical analogue: photon sphere microlasers
Chenni Xu, Aswathy Sundaresan, Nazire-Begüm Kazkal +7
The bell-like ringdown of the gravitational field in the last stage of the merging of massive black holes is now routinely detected on earth by the last generation of gravitational…
Exploring non-Euclidean photonics: Pseudosphere microlaser
H. Girin, S. Bittner, X. Checoury +8
Classical and wave properties of microlasers with the shape of a truncated pseudosphere are investigated through experiments and numerical simulations. These pseudosphere microlase…
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…
Möbius Strip Microlasers: a Testbed for Non-Euclidean Photonics
Yalei Song, Yann Monceaux, Stefan Bittner +9
We report on experiments with Möbius strip microlasers which were fabricated with high optical quality by direct laser writing. A Möbius strip, i.e., a band with a half twist, exhi…
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…
Three-dimensional micro-billiard lasers: the square pyramid
M. A. Guidry, Y. Song, C. Lafargue +8
Microlasers are of ample interest for advancing quantum chaos studies at the intersection of wave dynamics and geometric optics in resonators. However, the mode structures of three…
Dynamical control of square microlaser emission via symmetry classes
S. Bittner, A. Loirette-Pelous, C. Lafargue +5
A major objective in photonics is to tailor the emission properties of microcavities which is usually achieved with specific cavity shapes. Yet, the dynamical change of the emissio…
Waves and rays in plano-concave laser cavities, Part~II: a semiclassical approach
A. Pascal, S. Bittner, B. Dietz +6
This second paper on the Fabry-Perot cavity presents a semi-classical approach, which means that we consider the transition from wave optics to geometrical optics. The basic concep…
Unidirectional light emission from low-index polymer microlasers
M. Schermer, S. Bittner, G. Singh +3
We report on experiments with deformed polymer microlasers that have a low refractive index and exhibit unidirectional light emission. We demonstrate that the highly directional em…
Three-Dimensional Organic Microlasers with Low Lasing Thresholds Fabricated by Multiphoton Lithography
Vincent W. Chen, Nina Sobeshchuk, Clement Lafargue +12
Cuboid-shaped organic microcavities containing a pyrromethene laser dye and supported upon a photonic crystal have been investigated as an approach to reducing the lasing threshold…
Localized lasing modes of triangular organic microlasers
C. Lafargue, M. Lebental, A. Grigis +5
We investigated experimentally the ray-wave correspondence in organic microlasers of various triangular shapes. Triangular billiards are of interest since they are the simplest cas…
Gain properties of dye-doped polymer thin films
I. Gozhyk, M. Boudreau, H. Rabbani Haghighi +8
Hybrid pumping appears as a promising compromise in order to reach the much coveted goal of an electrically pumped organic laser. In such configuration the organic material is opti…
Three-dimensional emission from organic Fabry-Perot microlasers
Clément Lafargue, Stefan Bittner, Sergii Lozenko +5
We measured the far-field emission patterns in three dimensions of flat organic dye microlasers using a solid angle scanner. Polymer-based microcavities of ribbon shape (i.e., Fabr…
An insight into polarization states of solid-state organic lasers
