PHOTONIC CRYSTAL FIBERS AND METHODS FOR THE PRODUCTION THEREOF

摘要

The invention relates to photonic fibers and methods for the production thereof. 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.
