Abstract
The invention relates to an optical waveguide with at least one core region () extending along the longitudinal extent of the optical waveguide, and with a first jacket () which, viewed in the cross section of the optical waveguide, surrounds the core region (). The invention further relates to an optical arrangement with such an optical waveguide, and to a method for producing the optical waveguide. The object of the invention is to make available an optical waveguide for high-performance operation, which is improved in relation to the prior art in terms of mode instability. The invention achieves this object by virtue of the fact that the optical waveguide consists of crystalline material at least in the core region ().
