In this issue of Photonics Focus, we look at glass, of many types, and its fundamental role in optics and photonics. The issue explores a renaissance in freeform optics for a variety of innovative applications, hollow-core glass fibers that are speeding communications, and chalcogenides, a family of glass particularly suited to infrared sensing. Select articles are available online but the complete issue is downloadable as a PDF.
