摘要：
The present invention provides a curved optical waveguide with reduced loss. Particularly, it relates to a waveguide with rectangular cross-section which has a curved portion, wherein the relation between the width D of the waveguide at the curved portion and the radius R of the curvature is R/D.ltoreq.500. This waveguide is provided with at least one cladding inside the core of said curved portion, thereby dividing the waveguide at the curved portion in a plurality of narrow optical waveguides. This enables a large reduction of the loss even in curved optical waveguides with sharp curves, and realizes inexpensive optical waveguides.
