The invention relates to photonic fibers and methods for the production thereof. Said photonic fibers can be utilized especially for producing novel materials, structural elements, and devices and are used for forming short light pulses for nonlinear frequency conversion, as optical switches, and for controlling the dispersion of other nonlinear optical effects, for example. Examples of novel devices that can be produced by means of the inventive photonic fibers are wideband fiber lasers, magnetoresistors, and oscillators. A photonic fiber consists of a central area and ducts surrounding said central area and is characterized by the fact that at least two metallic conductors (2) are disposed near and along a central fiber (1). A photonic crystal fiber consists of a central fiber core and air ducts surrounding said central fiber core and is characterized in that at least six inner ducts are arranged so as to border the central fiber core while outer ducts are disposed so as to border the inner ducts. According to the inventive method for producing said photonic fibers, capillary elements and/or rods made of glass are combined into geometrical structures comprising at least one central fiber and an outer coating, said geometrical structures are heated and are subjected to a drawing process, and molten liquid metal is filled into hollow spaces of the capillary elements near the central fiber once the drawing process has been completed. |
