Information transduction based on magnons

We present an information transduction architecture that utilizes coherent interconversion between photons, magnons and electric charge carriers. The materials we use are low loss magneto-optic yttrium iron garnet (YIG). This device platform enables high fidelity communication devices, as well as small size microwave signal processing devices for Radar and defense related applications. Specific examples given here are widely tunable microwave oscillators, variable low loss delay lines, and high Q delay line oscillators.
