SPIE is the international society for optics and photonics, an educational not-for-profit organization founded in 1955 to advance light-based science, engineering, and technology. The Society serves more than 255,000 constituents from 183 countries, offering conferences and their published proceedings, continuing education, books, journals, and the SPIE Digital Library. In 2019, SPIE provided more than $5 million in community support including scholarships and awards, outreach and advocacy programs, travel grants, public policy, and educational resources.

A spicy silver lining

Distinctive thermal and electrical characteristics make silver nanoparticles perfect for optics and biosensing applications. One increasingly popular application for the nanoparticles is as an antibacterial coating. Silver ...

Super-resolution imaging with diagonal sampling

The charge-coupled device (CCD) revolutionized photography by enabling the capture of light electronically, as recognized by the 2009 Nobel Prize in Physics. However, CCD/CMOS pixel size has become a bottleneck for digital ...

Multidimensional, dual-channel vortex beam generator

Optical vortices, characterized by a helical phase front and doughnut-shaped intensity distribution, contribute to a broad range of applications, from microscopy to optical communications. And applications for optical vortices ...

Nanodots made of photovoltaic material support waveguide modes

Antimony sulfide, or stibnite (Sb2S3), has been investigated intensively in recent years as a promising material for nontoxic, environmentally friendly solar cells. It is now possible to fabricate thin photovoltaic films ...
