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. The waveguide connection can then be used with a waveguide, such as an optofiber, together with a light transmitter or light receiver.

Optical components intended for telecommunications purposes must be manufactured and mounted with a great degree of accuracy, since a component, such as an optochip, when mounted must be coupled optically, electrically, mechanically and thermally at the same time. In order to obtain a right-angled geometry when using surface-emitting or surface-detecting components, and to obtain a reduced optical travel path and accurate fixation of an optofiber, a reflective surface (12) which slopes at an angle of 45 degrees is arranged between a light-conducting core (16) and the active surface (10) of an optochip, and the light-conducting core has been placed closer to the reflective surface by bevelling the optofiber (9) and fitting the fiber in a V-groove and accurately fixating the fiber in the groove by means of a flat cover means (20). The aforesaid solutions relate generally to problems of a geometrical nature, but are able to provide important advantages in the arrangement of optical components in so-called optical micro-structures in comparison with earlier known techniques with regard to requirements of space, signal transmission performances and manufacturing costs.
