Encapsulation of optoelectronic components

A method for the manufacture of an optocomponent, comprising the steps of:

• producing a plate of an inorganic material,
• producing at least one cladding and at least one core associated said cladding at a surface of the plate for obtaining at least one waveguide, and
• mounting an optoelectronic component on said surface of the plate for optical coupling to the waveguides and for connection to electrical terminals,
• wherein a lower part of said at least one cladding and said at least one core are first produced by process technological methods at a top of a surface of the plate,
• an upper portion of the at least one cladding is produced by covering at least a portion of the surface of the plate including at least a portion of a free surface of the at least one lower cladding and at least a portion of a free surface of the at least one core with a plastics material, and
• wherein at least said surface of the plate including free surfaces of the cladding and the plastics material is coated with an additional plastics layer.

A method for the manufacture of an optocomponent comprising an optical connector means, comprising the steps of:

• producing a plate of an inorganic material,
• producing at least one waveguide at a surface of the plate,
• mounting an optoelectronic component on the surface of the plate for an optical coupling to the waveguides,
• producing accurately aligned guide grooves in the surface of the plate,
• coating at least a connection region between the component and at least one waveguide by molding thereon a transparent material having a selected refractive index to enhance the optical coupling between the component and the at least one waveguide, and
• molding on top of at least an area of the plate where the transparent material is coated a protective plastics layer.

An encapsulated optocomponent, comprising:

• a substrate of an inorganic material,
• an optoelectronic component mounted to a surface of the substrate optical coupling between the waveguides and for connection to electrical terminals,
• waveguides at least partly formed in and/or on the surface of the substrate, wherein the optoelectric component is optically coupled to the waveguides,
• a first plastics layer of an elastomer material covering at least a portion of the surface of the substrate including at least a portion of a free surface of the waveguides and a free surface of the optoelectronic component and
• a second plastics layer covering at least all of the first plastics layer on the surface of the substrate,
• wherein the material of the second plastics material has a high mechanical resistance to form a protection of the optoelectronic component and the waveguides and
• the material of the first plastics material is soft and has a high elasticity to relieve mechanical stresses resulting from temperature changes.
