Our Team


Carl Johnson

Executive Chairman

Carl founded II-VI Incorporated (Saxonburg, Pennsylvania USA) in 1971 to develop and manufacture II-VI compound semiconductor materials for optics and electro-optical applications in the then emerging, high-power laser arena. He served the company as its Principal Executive Officer and a Director for 36 years and continued as its Board Chairman for an additional 7 years.
During his career at II-VI, Carl oversaw and participated in or helped motivate company efforts to:

  • Develop and deploy the commercial scale manufacturing of highest-quality, laser-grade Cadmium Telluride (1971), Zinc Selenide (1975), Zinc Sulfide (1985) and diamond (2004)
  • Develop and deploy the commercial scale manufacturing of highest-quality,electronic-grade 3 inch (2004), 100 mm (2007) and 150 mm (2012) diameter SiliconCarbide substrates.
  • Since 2007, Carl has been active as a Primary Equity Investor and Director in 3emerging, technology-based businesses and serves as Board Chairman at two of those entities.

Carl attained a Bachelors Degree from Purdue University (USA) in 1964, the Masters Degree from Massachusetts Institute of Technology (USA) in 1965, and a Ph.D. Degree from the University of Illinois (USA) in 1969, all in the field of Electrical Engineering.
