SPIE Medical Imaging 2026 is a premier international symposium focusing on the latest research in medical image processing, physics, and computer-aided diagnosis. The event, which is in its 50th year, ...

Researchers at the Institute for Molecular Science (NINS, Japan) and SOKENDAI have demonstrated a more than 2000% voltage-induced enhancement of near-field nonlinear optical responses. To achieve this ...

Researchers developed a nonlinear nonlocal metasurface that converts infrared light to visible and steers it by combining ...

Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using ...

Metasurfaces in which nonlocal light-matter interactions take place are a potentially useful variant of traditional ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical ...

Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...
