| 英文摘要 | A laser module comprising a laser device attached to a heat sink that is configured to provide a relatively low thermal resistance for thermal management of the laser device, and a coefficient of thermal expansion (CTE) that is substantially matched to the CTE of the laser device for reducing stress caused by thermal cycles and bonding. In one embodiment, the heat sink comprises a substrate made out of a first material, and including one or more via holes filled with a second material distinct from the first material of the substrate. By properly selecting the first and second materials, configuring the overall mass of the substrate with respect to the overall mass of the filled via holes, and positioning and arranging the filled via holes with respect to the laser device, the desired effective thermal resistance and CTE for the heat sink may be achieved. In another embodiment, the laser module comprises a laser device attached to a submount, which is, in turn, attached to a heat sink. In this embodiment, the submount is configured as the heat sink discussed above. |
