“…For instance, one can expect the enhancement in the optical nonlinearity of the Fe−Ag system due to evanescent wave intensification at the magnetic− nonmagnetic interface through the Schoch effect (magnetoelastic origin) and/or Goos−Hanchen effect (electromagnetic origin). 66,67 The observation of large optical nonlinearity and strong nonlinear (photoinduced) polarization rotation effect on this system at the same wavelength of 1550 nm is very unique, suggesting a new "photon-spin-plasmon" interacting system and clearly demands this exciting system for further exploration.…”

There is a pressing need to discover optical and magneto-optical materials with better performance and lower cost that operate at telecommunication wavelengths. Here, we report the discovery of giant negative nonlinear refraction and nonlinear (photoinduced) Faraday rotation at 1550 nm using an array of bimetallic Fe−Ag nanopyramids. This system exhibited a very large third-order nonlinear refractive index (n 2 = −2.32 cm 2 /GW) and nonlinear figure of merit (F = 2.3). The same system also exhibited an extraordinarily large magneto-optical susceptibility (χ i 4 = 6.5 × 10 −12 esu) and nonlinear Faraday rotation up to 2.5 radian/μm at a magnetic field of 0.5 T. The nonlinear response was dependent on the degree of overlap of the Fe nanopyramid on the Ag nanopyramid, which influences the strength of plasmon-induced dipoles on the Ag nanopyramid. This nanoscale system opens up a rich set of possibilities in utilizing magnetoplasmonic materials to miniaturize future multifunctional devices such as frequency converters and Faraday rotators at telecommunication wavelengths.

“…While the EELS results strongly suggest a contribution from plasmon induced activity in the origin of the giant nonlinear properties of this metallic system, other mechanisms may still be important. For instance, one can expect the enhancement in the optical nonlinearity of the Fe-Ag system due to evanescent wave intensification at the magnetic/nonmagnetic interface through Schoch effect (magnetoelastic origin) and/or Goos-Hänchen effect (electromagnetic origin) [50,51]. The observation of large optical nonlinearity and strong nonlinear (photo-induced) polarization rotation effect on this system at the same wavelength of 1550 nm is very unique and clearly suggests an exciting system for further exploration.…”
