Patent ID: 7373070

Claim:
A package for an optical fiber device capable of carrying a high power signal, which comprises: a) a thermally conductive packaging substrate surrounding said optical fiber device and having an entry port through which one end of the optical fiber device enters the package and an exit port through which another end of the optical fiber device exits the package; b) a rigid transparent adhesive bond at the entry port and at the exit port anchoring each end of the optical fiber device to the packaging substrate, said adhesive bond being made of a material having a preselected coefficient of thermal expansion (CTE); and c) said packaging substrate is made of a material that has a CTE in relation to the CTE of the adhesive bond, such as to compensate for any variation in volume of said adhesive bond at each end of the optical fiber device due to temperature variation, thereby limiting mechanical stress in the optical fiber device within the package.
