An optical device package comprises an optical device (10) held in optically coupled relationship with an optical fibre (260) by a ceramic ferrule (60). The optical device (10) is mounted on heatsink (50), the heatsink being mounted on the ferrule (60). The optical device (10) is accurately mounted in relation to the rim of the ferrule (60) such that insertion of the optical fibre (260) into the ferrule brings the optical fibre into optically coupled relationship with the optical device without the need for active alignment techniques. The optical device (10), in use, is encapsulated in silicon sealant (40) to seal the device from the effects of humidity.

Boîtier comportant un dispositif optique (10) maintenu en communication optique avec une fibre optique (260) au moyen d'une bague céramique (60). Le dispositif optique (10) est monté sur un puits de chaleur (50) lui-même monté sur la bague (60). Le dispositif optique (10) est monté de manière précise par rapport au bord de la bague (60) de sorte que l'introduction de la fibre optique (260) dans la bague met la fibre optique en communication optique avec le dispositif optique sans que des techniques d'alignement actif ne soient nécessaires. Lors de son utilisation, le dispositif optique (10) est encapsulé dans une matière d'étanchéité en silicium (40) afin de protéger le dispositif contre les effets de l'humidité.
