Manufacturing of miniaturised three-dimensional electric components are presented, as well as components manufactured by the methods. The manufacturing methods comprise micro-replication of at least one master structure, e.g. via a mould structure, in at least one polymer layer onto which layer at least one conductive path is provided.

Method of manufacturing a miniaturized three- dimensional electric component

The present invention relates to an angled opto-mechanical connector ( ) and to a manufacturing process for the same. The connector ( ) comprises a fixture ( ) with straight and parallel grooves ( ) of two sizes running on the upper side of the fixture ( ) from a first fixture side ( ) to a second fixture side ( ). A lid ( ) is fastened above the fixture ( ). Fibre ends ( ) of optical fibres ( ) are placed in the capillaries which are formed between the smaller grooves ( ) of the fixture and the lid ( ) in such a way that they stick out through the side of the fixture ( ). A plastic capsule ( ) encloses the fixture ( ), the lid ( ) and the fibres ( ) completely or partially. The fibres ( ) stick out from the plastic capsule ( ) in a direction separated from that defined by the grooves of the fixture. The connector ( ) can also have an opto-mechanical interface of the above mentioned type at its other end ( ).

Angled opto-mechanical device

The present invention relates to a manufacturing method for an opto-mechanical connector (,) and to the connector itself. The invention includes that a fixture (,) is manufactured with straight and parallel grooves (,) running on the upper side of the fixture (,) from a first fixture side (,) to a second fixture side (,), and which grooves (,) are intended partly for optical fibers and partly for guide pins. A lid (,) is attached above the fixture (,), whereafter optical fibers (,) from, for example, a fiber ribbon cable (,) are introduced into the grooves (,) intended for the fibers from the first fixture side (,) so that the fiber ends (,) extend out through the second fixture side (,). Guide pins (,) are furthermore introduced into the grooves (,) intended for the guide pins. The structure obtained (fixture (,), lid (,), fiber ends (,) and guide pins (,)) is completely or partially enclosed by a plastic capsule (,).

Opto-mechanical device

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.
