Patent number: 5984534Abstract: Replicated polymeric microstructures have been used in the fabrication of optofiber waveguide connections, with the intention of simplifying the production of such connections, and therewith greatly reduce manufacturing costs. Fabrication is commenced from a silicon chip in which there has been etched grooves whose cross-sectional shape has been adapted to accommodate waveguides, such as optofibers. Firstly, the silicon chip is replicated, by plating the silicon chip with nickel for instance. The replication then serves as a model for producing a plastic copy of the silicon chip. This method of manufacture is able to produce waveguide accommodating grooves (2), such as optofiber accommodating grooves, to a very high degree of accuracy. Furthermore, the method provides a high degree of freedom in the configuration of the grooves, and also enables branched grooves for receiving branched fibres to be produced.Type: GrantFiled: March 24, 1997Date of Patent: November 16, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: H.ang.kan Elderstig, Olle Larsson, Goran Palmskog, Ove Ohman

Patent number: 5930438Abstract: The optoelectrical components which up to now have been used in the fibre-optical region have had waveguides of quartz and glass with hermetic encapsulating, which components have had too high manufacturing costs for profitable use. Through making polymeric single mode (SM) waveguides from plastic, for example, benzocyclobutene polymer (BCB) a simple reliable and inexpensive concept for making waveguides can be obtained. Two of the commercially available grades of BCB/DOW Chemicals have furthermore a refractive index difference which permits manufacturing of buried waveguides with SM characteristics. These two types of BCB material have shown themselves to be especially usable for manufacturing of so-called buried SM waveguides: a heat curable grade (1,4) used for under- and over-cladding for waveguides and a photo-definable derivative (3) used as the waveguide material.Type: GrantFiled: September 16, 1997Date of Patent: July 27, 1999Assignee: Telefonaktiebolaget LM EricssonInventors: Goran Palmskog, Olle Jonny Hagel, Goran Gustafsson, Paul Eriksen

Patent number: 5818990Abstract: An encapsulated optocomponent (1) comprises a single-crystal silicon wafer (3) and waveguides (9) located thereon, which at least partly are manufactured by means of process methods taken from the methods for manufacturing electronic integrated circuits. The waveguides (9) extend from an edge of the optoelectronic component (1) to an optoelectronic, active or passive component (11) attached to the surface of the silicon wafer (3). Over the region for connecting the waveguides (9) to the optoelectronic component (11) a transparent plastics material is molded (17), for instance an elastomer, having a refractive index adjusted to improve the optical coupling between the waveguides (9) and the optoelectronic component (11). The molding (17) covers advantageously all of said component (11) to also reduce thermal stresses between it and an exterior, protective layer (19) of a curable plastics material. The molded layer (17) can also cover the whole area of the waveguides (9) to form an upper cladding thereof.Type: GrantFiled: January 29, 1997Date of Patent: October 6, 1998Assignee: Telefonaktiebolaget LM EricssonInventors: Odd Steijer, Paul Eriksen, Hans Moll, Jan .ANG.ke Engstrand, Goran Palmskog, Mats Janson, Pia Tinghag

Patent number: 5715338Abstract: An 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.Type: GrantFiled: September 18, 1996Date of Patent: February 3, 1998Assignee: Telefonaktiebolaget LM EriccsonInventors: Sven Sjolinder, Odd Steijer, Goran Palmskog
