  • Integrated optics spot size converter and manufacturing method
    Patent number: 7317853
    Abstract: An optical component having a combination of optical waveguide elements for modifying the spot size of a mode of an electromagnetic field propagated by an optical waveguide element, the optical waveguide elements being formed on a substrate. The optical component further includes a first section having a first optical waveguide element, and a second section having at least two cooperating optical waveguide elements. The cooperating optical waveguide elements of the second section are configured to maintain optical coupling between the optical waveguide elements to ensure that at least one mode of the electromagnetic field is sustained by the at least two cooperating optical waveguide elements in cooperation.
