World record in photonic integration in silicon

July 01, 2013

Researchers at the Institut für Elektrische und Optische Nachrichtentechnik (INT), the Universität Stuttgart and the Institut für Mikroelektronik Stuttgart (IMS CHIPS) have reached a world record in the energy-efficient photonic integration in silicon. This is an important milestone in energy efficiency during online data transmission and telecommunication. The researchers work with optimized aperiodic nano-size grid structures equipped with a newly developed back mirror. This enabled a ground-breaking 87 percent result in the interface efficiency for light coming from standard glas fiber in integrated photonic wave ducts.
