Optical coupling device and fabricating method thereof

摘要

An optical coupling device (210) for coupling light to a core (242) of an optical waveguide device (240). The optical coupling device is connected to the core of the optical waveguide device at a first end (214) and convex at a second end (212) opposite the first. The optical coupling device includes a waveguide connecting the first and second ends of the optical coupling device, for light transmission, and a cladding (244) surrounding the waveguide. <IMAGE>
