Abstract

The present invention relates generally to optical waveguides for the transmission of electromagnetic energy. The present invention relates more particularly to optical fibers, optical fiber devices, and methods that can be used to remove cladding-propagating energy from a system. One embodiment of the invention is a rough-clad optical fiber section (100) having a first end (102) and a second end (104), the optical fiber section comprising a core (120) a glass cladding (130) disposed about the core, the cladding having an outer surface (132) having an rms surface roughness of at least about 100 nm, the outer surface not being immediately surrounded by polymer layer.
