Frequency dissemination with free-space optical links
, 2010 Optical clock technology is very certain to be integrated in the next high precision time standards. The demand for higher accuracy in time synchronization makes the use of free-space optical links necessary for frequency dissemination, especially if ...

Optical vortices in add-drop filters
Компьютерная оптикаIn this paper, we study the propagation of optical vortices (OVs) through an add-drop filter based on a multimode fiber. Using vector approximation and the transfer matrix formalism, we study the transmission of OVs through such a system.

Advanced Materials, EarlyView.The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Mechanically Programmable DNA Hydrogel Microparticles for 3D Cellular Systems
Advanced Materials, EarlyView.DNA hydrogel microparticles are designed to exhibit controllable viscoelasticity and stiffness across three orders of magnitude from 30Pa$30 \,\mathrm{Pa}$ to 6.5kPa$6.5 \,\mathrm{kPa}$. They are uptaken into fibroblast spheroids where they are actively remodeled by cellular forces depending on their mechanical properties.

Light transmission through a subwavelength slit: Waveguiding and optical vortices
, 2003 The anomalous (i.e., more than 100%) light transmission through a subwavelength slit in a thin metal plate is accompanied by a combination of waveguiding and phase singularities of the field of power flow near the slit.

Generation of Orbital Angular Momentum Beam Using Fiber-to-Fiber Butt Coupling
IEEE Photonics Journal, 2018 We experimentally demonstrate a simple scheme for broadband generation of orbital angular momentum (OAM) using a fiber-based structure. A standard single-mode fiber (SMF) is stuck to a two-mode fiber (TMF) with specific offsets and tilt angles to realize

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions
Advanced Materials, EarlyView.ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.
