A miniature co-extrusion technique, to produce a concentric multilayered glass fiber-optic preform of ~3 mm diameter, is modeled and experimentally demonstrated. A three-dimensional, incompressible, noncavitating, and nonisothermal Computational Flui... Read More about Predictive, Miniature Co-Extrusion of Multilayered Glass Fiber-Optic Preforms.

Mid-infrared fiberoptic devices and systems for in vivo medical diagnostics and surgery (2015)
Conference Proceeding
Seddon, A. B. (2015). Mid-infrared fiberoptic devices and systems for in vivo medical diagnostics and surgery. In 2015 IEEE Summer Topicals Meeting Series (SUM)doi:10.1109/PHOSST.2015.7248283

We are establishing a new paradigm in mid-infrared sensing, mapping and imaging to open up the mid-infrared for in vivo medical-diagnostics, for early diagnosis of cancer and mid-infrared endoscopic-monitoring of cancer-margins during surgery.

Low loss Ge-As-Se chalcogenide glass fiber, fabricated using extruded preform, for midinfrared photonics (2015)
Journal Article
