Photonic memory research at Eindhoven University of Technology

Researchers of the Institute of Photonic Integration of the Eindhoven University of Technology are developing a hybrid memory that combines photonic properties and magnetic hard drives.

The idea is to use femtosecond light pulses to write data directly in a magnetic memory.

"The switching of the magnetization direction using the single-pulse all-optical switching is in the order of picoseconds, which is about a 100 to 1000 times faster than what is possible with today's technology. Moreover, as the optical information is stored in magnetic bits without the need of energy-costly electronics, it holds enormous potential for future use in photonic integrated circuits," states Mark Lalieu, Ph.D. candidate at the Applied Physics Department of TU/e.
