Universal Broadband Linear Optical Transformations by an Interlaced Structured Integrated Photonic Processor
Ilya V. Kondratyev, Kseniia N. Urusova, Artem S. Argenchiev +8
Reconfigurable photonic integrated circuits enable applications in a wide range of fields. They represent a powerful platform for signal processing due to the ability to perform pa…
Thresholdless corner vortex solitons in fractal Sierpiński topological insulators
Yiqi Zhang, Alexander V. Kireev, Victor O. Kompanets +12
Quantized vortices are ubiquitous in physics, spanning superconductivity, astrophysics, superfluid condensed matter systems, and nonlinear optics. Yet embedding vorticity into topo…
Femtosecond laser written low-loss multiscan waveguides in fused silica
N. N. Skryabin, S. A. Zhuravitskii, I. V. Dyakonov +3
We report low-loss multiscan waveguides fabricated in fused silica using femtosecond laser writing technology. The multiscan principle allows to tailor the writing regime to excel…
Observation of nonlinear fractal higher-order topological insulator
Victor O. Kompanets, Hua Zhong, Yiqi Zhang +9
Higher-order topological insulators (HOTIs) are unique materials hosting topologically protected states, whose dimensionality is at least by a factor of 2 lower than that of the bu…
Broadband biphoton source for quantum optical coherence tomography based on a Michelson interferometer
Konstantin Katamadze, Anna Romanova, Denis Chupakhin +2
Broadband correlated photon pairs (biphotons) are valuable in quantum metrology, but current generation methods either involve complex nonlinear structures or lack sufficient bandw…
Large-scale error-tolerant programmable interferometer fabricated by femtosecond laser writing
Ilya V. Kondratyev, Veronika V. Ivanova, Sergey A. Zhuravitskii +8
We introduce a programmable 8-port interferometer with the recently proposed error-tolerant architecture capable of performing a broad class of transformations. The interferometer…
