Abstract
An optical coupling arrangement is provided, comprising a lightwave circuit (LC), a coupling element and an optical waveguide element, wherein the lightwave circuit has a first surface area and wherein the coupling element is attached to the first surface area) such that an optical signal can be transmitted from the lightwave circuit to the coupling element. The optical waveguide element is attached to the coupling element at a first junction zone such that the optical signal can be transmitted from the coupling element to the optical waveguide element). The coupling element is configured to perform mode transformation to the optical signal transmitted from the lightwave circuit to the optical waveguide element and such that adiabatic coupling of the optical signal to the optical waveguide element is enabled. Thus, a better coupling efficiency can be achieved.
