Abstract:
    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 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.
