Description
Summary:Interferometers are some of the most important optical devices, yet their spin wave based analogues so far received limited attention. In this work we demonstrate how one can design Mach-Zehnder Interferometer (MZI) operating on spin waves, and use to construct a spin wave version of a well known1 MZI based AI computing device. Modeling, performed both micromagnetically and by using a novel, finite difference based method, shows that some of the achievable operational parameters are orders of magnitude superior to both optical and CMOS based implementations.
