Estimating the term…
The invention relates to an arrangement and a method for efficient, non-linear light conversion. The object of the present invention of specifying an arrangement for efficient, non-linear light conversion, which simultaneously optimally fulfills the local conversion rate, the interaction scale, and the dispersive properties, is achieved in that the arrangement is provided in the form of a component, which comprises an optical waveguide or an optical fiber with or without cavities, wherein said arrangement consists of fiber cladding substrate or waveguide substrate (IV) with an adapted geometry, which defines the light-guiding properties of the fiber mode with designed dispersion properties (VI), and wherein the waveguide or the core carries a grown, atomically-thin layer of transition metal dichalcogenides in the form of crystallites, wherein this layer completely or partially covers the waveguide or the core.
A light conversion arrangement in a form of an optical fiber with a core and with or without cavities, consisting of a fiber cladding substrate or a waveguide substrate (IV) with an adapted geometry, which defines the light-guiding properties of the fiber mode with designed dispersion properties (VI), characterized in that a core carries a grown, atomically-thin layer of transition metal dichalcogenides in the form of crystallites, wherein the layer completely or partially covers the core, the crystallites are stochastically ordered, and the layer is located as a monolayer on a wave-guiding region of the core and is grown directly on the core of the fiber by chemical vapor deposition or atomic layer deposition.
