A coupling element (3) and a waveguide structure (4) are deposited on a common substrate (2) of an optical component (1). The coupling element (3) serves for the optical coupling of the waveguide structures (4) to a further optical component. The coupling element (3) contains a reflecting, curved surface...http://www.google.fr/patents/US7349601?utm_source=gb-gplus-shareBrevet US7349601 - Optical coupler
