Element magneto - plasmon a non - reciprocity modified, enhanced or reversed, component integrating of such elements, and method of manufacturing.

摘要

The present invention relates to a magneto - plasmon using a combination of layers including an optical guide layer and a magneto - optic in order to produce a non - reciprocal under the effect of a transverse magnetic field, comprising a structured network layer producing a non - reciprocity modified. The geometry of this network layer may be chosen to obtain a value of non - reciprocity chosen or enhanced in value and / or absorption, and also to obtain a non - reciprocity in absorption is inverted relative to an element comprising the same configuration of the layer without structuring. The present invention also relates to a component comprising a plurality of elements magneto - plasmonic to not - reciprocity thus modified, arranged on a single integrated component and subjected to a same magnetic field and, for example, an optical isolator to resonance in a ring or an optical circulator. It also relates to a method of manufacturing such a component or components, as well as a signal processing method using such an element or component.
