Very active and highly effective in the SBIR space from the firm's earliest days, in April 2000, NZ Applied Technologies (NZAT) was acquired by Corning Inc., and renamed Corning Applied Technologies. NZAT had focused around development and manufacture of photonic components for optical telecommunications applications including the optical data networks industry. The firm had been structured around manufacture of a line of solid-state VOAs that, at the time, were the fastest, most compact VOAs on the market today. The firm's development programs had included variable attenuator arrays, tunable optical filters, optical switches, and polarization controllers.
