Patent ID: 7729569

Claim:
An optical transmitter and receiver assembly comprising: at least one transmitter component ( 2 ); at least one receiver component ( 3 , 4 ); a lens ( 14 , 15 ) for the optical coupling of the at least one transmitter component or the at least one receiver component to an optical fiber; a planar optical circuit ( 5 ) consisting of one integrated waveguide ( 51 ); a first light signal from the at least one transmitter component ( 2 ) being coupled into the waveguide ( 51 ) of the planar optical circuit ( 5 ); and a second light signal being coupled out from the waveguide ( 51 ) of the planar optical circuit ( 5 ) and being guided onto the at least one receiver component ( 3 , 4 ), characterized in that: the at least one transmitter component ( 2 ) and the at least one receiver component ( 3 , 4 ) in this case being situated outside the plane in which the integrated waveguide ( 51 ) is formed in the planar optical circuit ( 5 ); the lens ( 14 , 15 ) being arranged on the planar 25 optical circuit ( 5 ); the first light signal being guided between the lens ( 14 , 15 ), on the one hand, and the at least one transmitter component ( 2 ) and the second light signal to the at least one receiver component ( 3 , 4 ) in the integrated waveguide ( 51 ); the lens ( 15 ) is arranged at the end side on an end area ( 55 ) of the planar optical circuit ( 5 ) and in this case in a manner directly adjoining the end area of the integrated waveguide ( 51 ) of the planar optical circuit ( 5 ); the lens ( 15 ) is fixed to the end area ( 55 ) of the planar optical circuit ( 5 ) by means of an indexed-matched adhesive; the lens ( 15 ) is formed as a planoconvex lens and the plane side ( 15 a ) is fixed to the end area ( 55 ) of the planar optical circuit ( 5 ); a plurality of receiver components ( 3 , 4 ) are provided and these in each case detect light having a different wavelength, the waveguide ( 51 ) in each case having coupling-out and deflection means ( 91 , 92 , 8 ) which couple out the received light for each received wavelength wavelength-selectively from the plane of the planar optical circuit ( 5 ) and guide it onto the assigned receiver component ( 3 , 4 ); and the coupling-out and deflection means are in each case formed by a Mach-Zehnder component ( 91 , 92 ) and an assigned deflection prism ( 8 ), light having a specific wavelength being coupled out from the waveguide ( 51 ) by the Mach-Zehnder component ( 91 , 92 ), being fed to the deflection prism ( 8 ) and being deflected by the latter onto the at least one receiver component ( 3 , 4 ).
