Spectral Signatures of Exceptional Points and Bifurcations in the Fundamental Active Photonic Dimer
Yannis Kominis, Vassilios Kovanis, Tassos Bountis
The fundamental active photonic dimer consisting of two coupled quantum well lasers is investigated in the context of the rate equation model. Spectral transition properties and ex…
Controllable Asymmetric Phase-Locked States of the Fundamental Active Photonic Dimer
Yannis Kominis, Vassilios Kovanis, Tassos Bountis
Coupled semiconductor lasers are systems possessing complex dynamics that are interesting for numerous applications in photonics. In this work, we investigate the existence and the…
Judiciously distributing laser emitters to shape the desired far field patterns
Constantinos A. Valagiannopoulos, Vassilios Kovanis
The far-field pattern of a simple one-dimensional laser array of emitters radiating into free space is considered. In the path of investigating the inverse problem for their near f…
Extreme waves and branching flows in optical media
M. Mattheakis, G. P. Tsironis
We address light propagation properties in complex media consisting of random distributions of lenses that have specific focusing properties. We present both analytical and numeric…
Manipulating polarized light with a planar slab of Black Phosphorus
Constantinos A. Valagiannopoulos, Marios Mattheakis, Sharmila N. Shirodkar +1
Wave polarization contains valuable information for electromagnetic signal processing and the ability to manipulate it can be extremely useful in photonic devices. In this work, we…
Magnified imaging based on non-Hermitian nonlocal cylindrical metasurfaces
Silvio Savoia, Constantinos A. Valagiannopoulos, Francesco Monticone +3
We show that a cylindrical lensing system composed of two metasurfaces with suitably tailored non-Hermitian (i.e., with distributed gain and loss) and nonlocal (i.e., spatially dis…
