A chiral inverse Faraday effect mediated by an inversely designed plasmonic antenna

Inverse Faraday effect in plasmonic heterostructures

The phenomenon of the surface plasmon assisted electromagnetic field concentration in the vicinity of the metal/dielectric interface of a periodically perforated with subwavelength holes arrays plasmonic structure is considered. An increase of the local stationary magnetic field appearing due to the inverse Faraday effect while the heterostructure is illuminated by circularly polarized light is...

Faraday effect in hybrid magneto-plasmonic photonic crystals.

We present a theoretical study of the Faraday effect in hybrid magneto-plasmonic crystals that consist of Au-Co-Au perforated membranes with a periodic array of sub-wavelength holes. We show that in these hybrid systems the interplay between the extraordinary optical transmission and the magneto-optical activity leads to a resonant enhancement of the Faraday rotation, as compared to purely ferr...

Negative Reflection in a Faraday Chiral Medium

The four wavenumbers associated with planewave propagation in a Faraday chiral medium (FCM) with relatively huge magnetoelectric coupling give rise to enhanced possibilities for negative–phase–velocity propagation and therefore negative refraction. They can also give rise to the phenomenon of negative reflection. In particular, for a nondissipative example, we deduced that an incident plane wav...

Investigation of the femtosecond inverse Faraday effect using paramagnetic Dy3Al5O12

Magnetization dynamics in dysprosium orthoferrites via the inverse Faraday effect

The ultrafast nonthermal control of magnetization has recently become feasible in canted antiferromagnets through photomagnetic instantaneous pulses A. V. Kimel et al., Nature 435, 655 2005 . In this experiment, circularly polarized femtosecond laser pulses set up a strong magnetic field along the wave vector of the radiation through the inverse Faraday effect, thereby exciting nonthermally the...
