Luxtera

Luxtera is a company that develops fabless silicon photonics semiconductors to be used for complementary metal–oxide–semiconductors (CMOS) technology. Luxtera was established by Cary Gunn. It aims to offer a high-performance and low-cost materials for computing equipment. The company was acquired by Cisco in 2018 and is now operating as its subsidiary. Luxtera is based in Carlsbad, California.

There are two main product groups that were designed by Luxtera – the 100G-PSM4 and the 2x100G-PSM4 OptoPHY. Both of these modules are used for CMOS purposes to manufacture processors, RAM, and digital logic circuits (Wikipedia). The difference between the two Luxtera products lie in the higher performance and flexibility of the 2x100G-PSM4 OptoPHY, in comparison to the 100G-PSM4.

Before Luxtera was acquired by Cisco for $660 million, it managed to raise capital through six funding rounds until March 2014; accumulating a total amount of $130.7 million. Past investors include Lux Capital, New Enterprise Associates, August Capital, and Sevin Rosen Funds.
