Abstract
A device for attenuating cladding modes in a single mode optical fiber is disclosed. The device comprises two supports, each equipped with spaced apart corrugations. The optical fiber lies transversely across the corrugations and the two supports are clamped together to impart micro-bends to the optical fiber. The resulting micro-bends provide excellent cladding mode attenuation and the spacing of the corrugations and support members can be adjusted so that the core modes are not attenuated.
