PCT No. PCT/GB95/01542 Sec. 371 Date Jan. 14, 1997 Sec. 102(e) Date Jan. 14, 1997 PCT Filed Jun. 29, 1995 PCT Pub. No. WO96/00918 PCT Pub. Date Jan. 11, 1996An optical device package includes an optical device held in optically coupled relationship with an optical fibre by a ceramic ferrule. The optical device is mounted on a heatsink, the heatsink being mounted on the ferrule. The optical device is accurately mounted in relation to the rim of the ferrule 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, in use, is encapsulated in silicon sealant to seal the device form the effects of humidity.
