Title:
SPACER FOR ATTACHING COEFFICIENT OF THERMAL EXPANSION MISMATCHED COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2022/267404
Kind Code:
A1
Abstract:
An optical device (100) including a base (305, 406) with a first coefficient of thermal expansion. The optical device (100) may include an opto-mechanical component (310, 402) with a second CTE attached to a surface of the base (305, 406) via a solder layer (126, 315, 404). The first CTE and the second CTE may differ by greater than a threshold amount. A spacer (128, 320, 408) may be disposed within the solder layer (126, 315, 404) to attach the opto-mechanical component (310, 402) to the base (305, 406).
