📢 We are delighted to announce that Prof. Dr. Yuri Kivshar from The Australian National University, Australia, will serve as a Keynote Speaker for the 2nd International Online Conference on Photonics (#IOCP 2026), which will be virtually held in from 14 to 16 December 2026. 🎤 Prof. Dr. Yuri Kivshar is Distinguished Professor at the Australian National University. His research focuses on nonlinear physics, nonlinear photonics, and the physics of metamaterials, and he has published numerous high-impact papers in Physical Review Letters and Nature-family journals. His key academic contributions include pioneering findings on nonlinear localized modes in optical systems, optical solitons and vortices, localization in discrete systems, as well as nonlinear effects in plasmonics and metamaterials. 🎤And We are honored to present our interview with Prof. Dr. Yuri Kivshar: 1. What first sparked your interest in this field, and who or what has been most influential in shaping your research journey? I changed the research topics four times, from solitons to photonic crystals and metamaterials. Currently I am working in the field where I help pioneering, resonant metaphotonics 2. Could you describe your current research focus and share any recent developments or key findings with us? We are interested in photonic structures that gain their functionalities from the concepts of metamaterials, and both electric and magnetic multipolar resonances. More recently, we have been working on chiral properties and discovered the so-called chiral bound states in the continuum 3. What major challenges have you encountered in your research, and how have you addressed them? One of the challenges was to understand why and when the structures become chiral, we approached this from the perspective of symmetry, and some of the finding were done accidentally 4. In your view, what distinguishes IOCP 2026 from other conferences in the field? As the keynote speaker and scientific advisory board member, what do you hope this conference will offer to scholars and researchers worldwide? Do not need to travel, the zoom format can be beneficial in some form It may broaden their research horizons, and may help establish new (on line) contacts 5. What do you see as the most important emerging or “hot” topics in photonics and/or nonlinear optics and photonics over the next few years, and why? High-harmonic generations: Not yet fully understood, also the effects of structured media and resonances Topological effects in photonics: Topology brings many surprises that can be observed with optics Novel materials: Optical quantum materials and merging of optics and solid state physics 🔗 Conference website: https://t.ly/KkUpg 📝 Submit your abstracts NOW: https://t.ly/zfxc5 #MDPIConference #openaccess #Photonics #Mietronics #Mieresonances #Boundstatesinthecontinuum #Chiralmetasurfaces

#Highlyviewedpaper 📖 Progress in Passive Silicon Photonic Devices: A Review ✍ By Qidi Liu, Ethan Y. Bian and Jiawei X. 🏘️ From The University of Georgia and Penn State University 👉 https://t.ly/mUt27 ✨ This paper provides a comprehensive review of recent progress in the foundational passive devices that underpin this technological revolution. We survey the state of the art in fundamental building blocks, including strip, rib, and silicon nitride waveguides, with a focus on achieving ultra-low propagation loss. The review details essential components for light coupling and splitting, such as grating couplers, edge couplers, multimode interference couplers, and directional couplers, citing their typical performance metrics. Key wavelength filtering and routing components, including high-Q ring resonators, Mach–Zehnder interferometers, and arrayed waveguide gratings, are analyzed. #Photonics #Optics #SiliconPhotonics #IntegratedOptics

📖 Theoretical Study of the Pre-Plasma Density Scale Length’s Influence on the Absorption Efficiency in Laser–Solid Interaction at Relativistic Laser Intensities for PW-Class Lasers ✍ By Iuliana-Mariana Vladisavlevici, Michael Ehret, Evgeny Filippov, Enrique García-García, Cruz Méndez, Marta Olivar Ruiz, Óscar Varela, luca volpe and Jose Antonio Pérez-Hernández 🏘️ From CLPU. CENTRO DE LÁSERES PULSADOS, ELI - Extreme Light Infrastructure and Universidad Politécnica de Madrid ✨ This work studied the pre-plasma that builds up in interactions of focused high-power PW-class lasers with solid targets at the target surface facing the laser beam, and its impact on the global laser absorption efficiency as well as on the spectral cut-off energy of laser-generated proton beams. Our practical heuristic estimates were derived from the example of the VEGA-3 laser at CLPU. Our modeling results for the pre-plasma expansion due to the laser pedestal of VEGA-3 were benchmarked by hydrodynamic simulations, revealing good agreement for the evolution before the arrival of the main Gaussian laser intensity peak. Our detailed numerical two-dimensional Particle-in-Cell simulations showed the impact of different pre-plasma scale lengths on the absorption efficiency of laser energy into electrons, relevant for the seeding of other types of radiation. It was shown that the absorption can increase manyfold when increasing the pre-plasma scale length. This effect can be beneficial for the spectral cut-off energy of accelerated protons, where a trade-off between absorption and electron dynamics yields an optimum pre-plasma scale length. The findings can be applied to other PW-class laser facilities. 👉 https://t.ly/iiI8_ #Photonics #Optics
