This is the only technical page on this site, and I've selected just a single topic. It's about hollow core fibers. I've been working on this subject for well over 20 years: over that period it has become a genuinely important subject.

 

Hollow core fibers formed from silica and with a structured cladding are demonstrating their potential to be a transformative technology in enabling light-based manufacturing. They are the only way that powerful ultrashort optical pulses can be transmitted flexibly from their source to the workpiece, with neither temporal nor spectral degradation. The picture on the left shows an early demonstration of this capability.

 

The field has made tremendous progress over the last few years, with some different fiber designs demonstrated illustrated on this page but there is still a lot of research to do.
