FUNCTIONALIZED ELASTOMER STEP-INDEX OPTICAL FIBRE AND METHOD FOR PRODUCING STEP-INDEX OPTICAL FIBRES

摘要

A method for producing elastomeric optical waveguides, in particular optical fibers, comprises providing a hollow body (10) with at least one hollow channel (13) extending along a first direction (13); Forming a fiber sheath (20, 21, 22) in the hollow channel (11) by coating the inner wall (12) of the hollow channel (11) with at least one first uncrosslinked, flowable elastomer mixture under the action of a force acting in the first direction, wherein a cavity ( 29) surrounded by the fiber cladding (20, 21, 22) remains; Forming a fiber core (30) in the cavity (29) by filling the cavity (29) with another uncrosslinked flowable elastomer mixture; and forming an optical waveguide (100) comprising the fiber cladding (20, 21, 22) and the fiber core (30) by curing the fiber cladding (20, 21, 22) and the fiber core (30).
