Sunnyvale-based Juniper Networks announced Aug. 4 in a quarterly filing with the Securities and Exchange Commission it acquired Santa Barbara-based silicon photonic chip maker Aurrion for $165 million.

Aurrion makes components that transmit information quickly using cheap, easily mass-produced silicon wafers. UC Santa Barbara professor John Bowers founded Aurrion in 2008 and the company quickly spun off from UCSB. Bowers still serves as chairman of Aurrion’s board of directors and the company employs about 60 people.

Prior to its sale, the company raised about $20 million in capital. Its last was an $11.5 million raise completed in September 2014.

Founded in 1996, Juniper Networks develops and markets products for computer networks including routers, switches and network security products.
