Optics and photonics are technical enablers for many areas of the economy, and dramatic technical advances have had a major impact on daily life. For example, in the last decade, advances in optical ...

New experiments are pushing our understanding of light and optics to the limit and are also opening up new areas of physics and novel applications. (Picture credit: Photodisc) Optics has always been ...

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, ...

In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...

IT was (Ji surprise to read in Dr. Cosslett's preface that a course of lectures in electron optics has seen given in the honours physics course at Oxford since 1942; yet the surprise was unwarranted ...
