Abstract
A coupling waveguide is interconnected between a launching fiber and a receiving fiber to reduce coupling loss. The coupling waveguide includes an integrally formed graded index lens having a non-parabolic refractive index profile. The graded index lens receives as an input a coupling mode field of an optical signal launched by the launching fiber and transforms the coupling mode field into a transverse spatial distribution matching a corresponding coupling mode field of the receiving fiber.
