Abstract
Die Erfindung betrifft einen optischen Übergang zwischen zwei optischen Schichtwellenleitern. Dazu ist eine Anordnung vorgesehen aus einem ersten optischen Schichtwellenleiter (2) und einem zweiten optischen Schichtwellenleiter (3), wobei der erste optische Schichtwellenleiter (2) und der zweite optische Schichtwellenleiter (3) voneinander verschiedene über ihre jeweilige Länge konstante Dicken (d, r) aufweisen, der erste optische Schichtwellenleiter (2) mit dem zweiten optischen Schichtwellenleiter (3) mittels einer optischen Schichtwellenleiterstruktur (4) verbunden ist, die über ihre gesamte Länge (w) eine Dicke (h) aufweist, die zwischen der Dicke (d) des ersten optischen Schichtwellenleiters (2) und der Dicke (r) des zweiten optischen Schichtwellenleiters (3) liegt. Erfindungsgemäß ist die Dicke (h) der optischen Schichtwellenleiterstruktur (4) über die gesamte Länge (w) der optischen Schichtwellenleiterstruktur (4) konstant. Damit wird eine Möglichkeit für einen effizienten und mit geringen Verlusten behafteten Übergang zwischen zwei optischen Schichtwellenleitern mit unterschiedlicher Dicke bereitgestellt.
The invention relates to an optical junction between two optical planar waveguides. For this purpose, an arrangement is provided of a first optical layer waveguide (2) and a second optical slab waveguide (3), wherein the first optical layer waveguide (2) and the second optical slab waveguide (3) different from each other is constant over their respective length of thicknesses (d, r ) which the first optical layer waveguide (2) with the second optical film waveguide (3) (by means of an optical layer waveguide structure 4) is connected, which (along their entire length w) has a thickness (h) which is between the thickness (d) the first optical waveguide layer (2) and the thickness (r) of the second optical waveguide layer (3). According to the invention, the thickness (h) of the optical layer waveguide structure (4) over the entire length (w) of the optical layer waveguide structure (4) constant. Thus, a possibility for an efficient and entailing low loss transition between two optical planar waveguides is provided with different thickness.
