ABSTRACT:
In the optical connection of telecommuniation glass fibres to semiconductors a curable composition is used which comprises a polyester urethane acrylate or a polyether urethane acrylate. The composition furthermore comprises a heat- or light-activatable initiator.
The refractive index of the cured connecting material is adjusted by the addition of both a reactive diluent which increases the refractive index and a reactive diluent which decreases the refractive index. Said reactive diluents furthermore serve to establish the desired mechanical properties of the connecting material prior to and after curing.
The curable composition is provided on the glass fibres and/or on the semiconductor laser, after which they are contacted with each other and are optically aligned. The composition is then cured by raising the temperature or by exposure to light.
