One of the major limitations of optics-based systems at present is that, at a certain point, they still need to have electronics-based transistors to efficiently process the data. Now, a team led by Alireza Marandi, Assistant Professor of Electrical Engineering and Applied Physics, has created an all-optical switch. Such a switch could eventually enable data processing using photons. Device nanofabrication was performed at the Kavli Nanoscience Institute (KNI) at Caltech. [Caltech story]
