Title: OPTICAL WAVEGUIDE HAVING A WEAKLY-CONFINING WAVEGUIDE SECTION AND A STRONGLY-CONFINING WAVEGUIDE SECTION OPTICALLY COUPLED BY A TAPERED NECK
Abstract:
An optical waveguide includes a first waveguide section (5) providing weak confinement of an optical signal in a direction generally transverse to its propagation direction, a second waveguide section (7) providing strong confinement of the optical signal in all directions relative to the propagation direction, a tapered neck (3) between the first and second waveguide sections to optically couple those waveguide sections, and a core defined through the first and second waveguide sections and tapered neck, and through which the optical signal may propagate in the propagation direction. A method for making such an optical waveguide.
