We report on the first demonstration of a proof-of-principle optical fiber ‘meta-tip’, which integrates a phase-gradient plasmonic metasurface on the fiber tip. For illustration and validation ...

Figure 1. Photothermal synergistic TPP hydrogen detection system integrated at the tip of an optical fiber. (a) A 3D schematic of the fiber-optic TPP tip illuminated simultaneously by a halogen light ...

Ultrasound neuromodulation, as a technique for controlling neural activity, has garnered increasing attention in recent years. However, when transmitted externally, ultrasound encounters significant ...

(Nanowerk Spotlight) Electronic devices have gotten much smaller and more efficient over the years but the design and underlying physics of today's optical lenses haven't changed much since antiquity.
