Working with his colleagues, he invented transparent LaF3 glass ceramics, passivation coatings for CaF2 excimer laser optics, high strain point LCD display glasses, and an all fiber filter to suppress multi path interference in Erbium doped fiber amplifiers. Matt developed new fiberization techniques for soft glass and used these novel methods to make fiber lasers and broad band amplifiers. He co-invented the tapered fiber laser and fabricated high NA rectangular core Ytterbium doped fibers that delivered 1W of 980 nm single mode output. In 2005 he earned the Karl Schwartzwalder Professional Achievement in Ceramic Engineering (PACE) Award. Matt has organized seven sessions, one symposium, and the 2006 Glass & Optical Materials Division Meeting. Currently he is investigating chemically strengthened glasses and is a co-inventor of Gorilla® Glass. He is the author or co-author of 40 papers, 2 book chapters, and holds 64 patents.
