A magneto-electro-optical effect in a plasmonic nanowire material
A magneto-electro-optical effect in a plasmonic nanowire material
Electro- and magneto-optical phenomena play key roles in photonic technology enabling light modulators, optical data storage, sensors and numerous spectroscopic techniques. Optical effects, linear and quadratic in external electric and magnetic field, are widely known and comprehensively studied. However, optical phenomena that depend on the simultaneous application of external electric and magnetic fields in conventional media are barely detectable and technologically insignificant. Here we report that a large reciprocal magneto-electro-optical effect can be observed in metamaterials. In an artificial chevron nanowire structure fabricated on an elastic nano-membrane the Lorentz force drives reversible transmission changes upon application of a fraction of a Volt when the structure is placed in a fraction-of-Tesla magnetic field. We show that magneto-electro-optical modulation can be driven to hundreds of thousands cycles per second promising applications in magneto-electro-optical modulators and field sensors at nano-Tesla levels

Abstract
Electro- and magneto-optical phenomena play key roles in photonic technology enabling light modulators, optical data storage, sensors and numerous spectroscopic techniques. Optical effects, linear and quadratic in external electric and magnetic field, are widely known and comprehensively studied. However, optical phenomena that depend on the simultaneous application of external electric and magnetic fields in conventional media are barely detectable and technologically insignificant. Here we report that a large reciprocal magneto-electro-optical effect can be observed in metamaterials. In an artificial chevron nanowire structure fabricated on an elastic nano-membrane the Lorentz force drives reversible transmission changes upon application of a fraction of a Volt when the structure is placed in a fraction-of-Tesla magnetic field. We show that magneto-electro-optical modulation can be driven to hundreds of thousands cycles per second promising applications in magneto-electro-optical modulators and field sensors at nano-Tesla levels
