September 17, 2012 – CrossFiber, a San Diego, CA maker of photonic switches that incorporate microelectromechanical system (MEMS) technology, says it has completed the final tranche of a Series D round of funding, which closes totaling $13.4 million. Southern Cross Venture Partners led the funding round, with participation from New Venture Partners and Arsenal Venture Partners, as well as existing investors including Back Bay Management and PacifiCap.

The majority of the funds has been and will be used to rapidly expand manufacturing capacity for CrossFiber’s LiteSwitch family of photonic switches, according to the company. The LiteSwitch photonic switches combine 3D MEMS micro-mirrors on silicon, non-invasive beam steering (NIBS), and custom ASICs, for application in data centers and fiber-optic switching. The company says its proprietary methods create precisely positioned fiber and microlens arrays, yielding collimator arrays with good beam shape and low insertion loss.
