The generation of tunably focused light at remote locations is a critical photonic functionality for a wide range of applications. Here, we present a novel concept in the emerging field of Metafibers that achieves, for the first time, fast, alignment-free, fiber-integrated spatial focus control in a…
This study presents what we believe to be a novel 37-core multicore fiber designed for the visible range (565 nm … 650 nm), featuring a hexagonal arrangement of identical cores, single-mode guidance, low intercore crosstalk, low-mode attenuation (< 0.1 dB/m), and high-core density (1.2 × 10-3). Experimental…
Abstract This study introduces fiber-assisted nanoparticle tracking analysis (FaNTA) as a platform for nanorheology that utilizes an advanced antiresonant optical fiber to analyze the viscoelastic properties of fluids at the nanoscale. The platform confines colloidal nanotracers within a fiber-integrated…
In this study, we present an unexplored approach for remote focus manipulation using 3D nanoprinted holograms integrated on the end face of multi-core single-mode fibers. This innovative method enables precise focus control within a monolithic metafiber device by allowing light coupled into any of the…
