Structured light has revolutionized optical beam shaping, allowing for advanced control over phase, polarization, and orbital angular momentum (OAM). However, the generation and manipulation of non -separable spin–orbit states often rely on bulky and complex optical setups. Metasurfaces overcome these limitations, offering compact, planar devices with complete control of phase and polarization...
Optical tweezers use highly focused light beams to manipulate microscopic objects and measure forces at the single-molecule level, enabling precise investigation of biomolecular structure and dynamics [1]. By applying controlled mechanical stimuli, this technique reveals elastic, kinetic, and energetic properties of DNA, RNA, and proteins as they undergo biochemical reactions. In this talk, we...
Optical fibers can act as continuous sensors, turning guided light into a tool to measure temperature, strain, and vibration along their entire length. Originally developed for large-scale monitoring of structures and the environment, distributed fiber sensing has recently advanced to millimeter-scale spatial resolution, opening the door to high-resolution, minimally invasive measurements in...
