Abstract
A single free-beam region for coupling electromagnetic radiation in and out is provided in order in the case of an AWG coupler for spectrally separating electromagnetic radiation to achieve a more stable thermal characteristic and a space-saving layout.
Claims9
An AWG coupler for spectrally separating electromagnetic radiation, defined by a 1-to-N transmission region (16) for coupling in and coupling out electromagnetic radiation, in the case of which the arms (4 to 12) of the AWG coupler (1, 1′) that define the optical path length difference are coupled to an exit surface (15.) and an entry surface (14) of the star coupler (16), and the arms (4 to 12) of the AWG coupler (1, 1′) that define the optical path length difference lie on a lobar line.
The AWG coupler as claimed in one of the preceding claims, wherein a plurality of sets of arms(4 to 12;
- 4′ to 12′) are in each case assigned, in a fashion angularly offset in groups in each case, to a group of entering electromagnetic radiation and exiting electromagnetic radiation.
The AWG coupler as claimed in one of the preceding claims, wherein the AWG coupler (1, 1′) is designed as a two-dimensional surface wave conductor.
The AWG coupler as claimed in one of the preceding claims, wherein the AWG coupler (1, 1′) is applied to a substrate as a PECVD layer system, in particular as a PICVD layer system.
A telecommunications system comprising an AWG coupler (1, 1′) as claimed in one of the preceding claims.
