Lumentum Holdings, formerly part of JDS Uniphase, is a California-based technology firm. Its predecessor spun off its fiber-optic solutions as Lumentum Holdings in August 2015 and renamed itself as Viavi Solutions. Lumentum provides two types of optical and photonic products: optical components that are used in telecommunications networking equipment, and commercial lasers for manufacturing, inspection and life-science lab uses. The firm is also expanding into new optical applications, such as 3-D sensing laser diode for consumer electronics.
