Abstract
An opto-electronic device is provided wherein an optical assembly having a first coefficient of thermal expansion is connected to a substrate having a second, different coefficient of thermal expansion. A plurality of stakes are either separately inserted or integrally formed-in the optical assembly and extend through and are adhesively bonded to passageways formed in the substrate. The stakes reduce or prevent differential thermal expansion that would otherwise occur as the device heats up during operation. The substrate may be thermally connected to a metallic housing for the device to increase transfer of unwanted heat into the ambient atmosphere.
