The CMOS technology is nearing its limits as the dimensions of the devices reach the atomic scale. Spin waves are a prospective beyond-CMOS concept, which promises a significant reduction of power consumption and a change of paradigm to wave-based computing. One of the biggest challenges to tackle before commercialization is the effectivity of nanoscale spin wave excitation. This project proposes a novel approach to detect parametrically pumped (amplified) nanoscale spin waves using the Mie-enhanced Brillouin light scattering technique.
