ABSTRACT:
A bent waveguide for an optical integrated circuit includes a core region, cladding regions disposed at both sides of the core regoin forming a waveguide including a bent portion comprising the core region and the cladding region, a local waveguide region in the cladding region at the inner side of the bent portion. The local waveguide region has a larger refractive index than that of the core region or than that of the cladding region.
