PHOTONIC-MRAM: from fundamentals to nanoscale engineering – Presented by Theo Rasing, Radboud University, at the Photonic Integration Conference 2018, which will take place on October 2, at High Tech Campus Eindhoven, The Netherlands.

The 21st century digital economy and technology is presently facing fundamental scaling limits (heating and the superparamagnetic limit) as well as societal challenges: the move to mobile devices and the increasing demand of cloud storage leads to an enormous increase in energy consumption of our ICT infrastructure. These developments require new strategies and paradigm shifts, such as photon- and spin-based technologies. Since the demonstration of All-Optical Switching (AOS) by a single 40 femtosecond laser pulse1, the manipulation of spins by ultra-short laser pulses has become a fundamentally challenging topic with a potentially high impact for future spintronics3,4, data storage and quantum computation2. AOS in principle provides an alternative and energy efficient approach to magnetic recording, but in order to turn AOS into a viable technology, a number of challenges have to be overcome, such as scaling the technique to the nanoscale5, and delivering the required light in an efficient manner. In this talk, recent progress in this direction will be discussed. Continue reading “PHOTONIC-MRAM: from fundamentals to nanoscale engineering – Presented by Theo Rasing, Radboud University”
