Coherence properties of light in highly multimoded nonlinear parabolic fibers under optical equilibrium conditions
Mahmoud A. Selim, Fan O. Wu, Georgios G. Pyrialakos +2
We study the coherence characteristics of light propagating in nonlinear graded-index multimode fibers after attaining optical thermal equilibrium conditions. The role of optical t…
Complex Skin Modes in Non-Hermitian Coupled Laser Arrays
Yuzhou G. N. Liu, Yunxuan Wei, Omid Hemmatyar +4
From biological ecosystems to spin glasses, connectivity plays a crucial role in determining the function, dynamics, and resiliency of a network. In the realm of non-Hermitian phys…
Observation of Chiral State Transfer Without Encircling an Exceptional Point
Hadiseh Nasari, Gisela Lopez-Galmiche, Helena E. Lopez-Aviles +7
The adiabatic theorem, a corollary of the Schrödinger equation, manifests itself in a profoundly different way in non-Hermitian arrangements, resulting in counterintuitive state tr…
Direct Modulation of Electrically Pumped Coupled Microring Lasers
Chi Xu, William E. Hayenga, Demetrios N. Christodoulides +2
We demonstrate how the presence of gain-loss contrast between two coupled identical resonators can be used as a new degree of freedom to enhance the modulation frequency response o…
Parity-time symmetric optical neural networks
Haoqin Deng, Mercedeh Khajavikhan
Optical neural networks (ONNs), implemented on an array of cascaded Mach-Zehnder interferometers (MZIs), have recently been proposed as a possible replacement for conventional deep…
Majorana Bound State Cavities
Babak Bahari, Jae-Hyuck Choi, Yuzhou G. N. Liu +1
Cavities play a fundamental role in optical physics by providing spatio-temporal confinement of energy that facilitates light-matter interactions. They are routinely utilized in a…
Gain Induced Topological Response via Tailored Long-range Interactions
Yuzhou G. N. Liu, Pawel S. Jung, Midya Parto +2
The ability to tailor the hopping interactions between the constituent elements of a physical system could enable the observation of unusual phenomena that are otherwise inaccessib…
Topological Modes in a Laser Cavity through Exceptional State Transfer
A. Schumer, Y. G. N. Liu, J. Leshin +8
Shaping the light emission characteristics of laser systems is of great importance in various areas of science and technology. In a typical lasing arrangement, the spatial profile…
Bimorphic Floquet Topological Insulators
Georgios G. Pyrialakos, Julius Beck, Matthias Heinrich +5
Topological theories have established a new set of rules that govern the transport properties in a wide variety of wave-mechanical settings. In a marked departure from the establis…
A thermodynamic description of the near- and far-field intensity patterns emerging from multimode nonlinear waveguide arrays
Mahmoud A. Selim, Fan O. Wu, Huizhong Ren +2
Nonlinear highly multimode photonic systems are ubiquitous in optics. Yet, the sheer complexity arising from the action of nonlinearity in multimode environments has posed theoreti…
Optical Thouless pumping transport and nonlinear switching in a topological low-dimensional discrete nematic liquid crystal array
Pawel S. Jung, Midya Parto, Georgios G. Pyrialakos +6
We theoretically investigate a Thouless pumping scheme in the 1D topological Su-Schrieffer-Heeger (SSH) model for single and multiple band-gaps systems when implemented in a discre…
