PCT No. PCT/SE95/00282 Sec. 371 Date Sep. 18, 1996 Sec. 102(e) Date Sep. 18, 1996 PCT Filed Mar. 20, 1995 PCT Pub. No. WO95/25975 PCT Pub. Date Sep. 28, 1995An impermeable encapsulated optocomponent and a method for encapsulating an optocomponent includes providing a base, preferably of silicon, supporting waveguides and an optoelectronic component optically coupled to each other. The optoelectronic component is connected to electric driver circuits. Thereafter a silica layer is deposited over a region of the substrate including at least the coupling of the waveguide and optoelectronic component, after which it is encapsulated by applying a layer of curable plastics material. The deposition of silica provides an impermeable inner encapsulation layer and prevents, when applying the curable plastics material, plastics from penetrating between the inner ends of the waveguides and the optoelectronic component, and thus the optical coupling is secured therebetween. |
