Thermal management for the continuous wave (CW) operation of large-area double-lattice photonic-crystal surface-emitting lasers (PCSELs) is discussed. Thermal analysis is conducted to calculate the temperature of PCSELs under CW operation with heat dissipation. We assemble a double-lattice PCSEL in a water-cooling package with a highly thermally conductive sub-mount for heat dissipation. We measure the device temperature by using a thermographic camera and compare the measured values with the calculations. Owing to proper heat dissipation, we successfully realize ${\sim}{{8}}\;{\rm{W}}$ of output power under CW operation of a single-chip double-lattice PCSEL.

大面积双晶格光子晶体激光器连续波操作的热管理

讨论了大面积双晶格光子晶体表面发射激光器（PCSEL）的连续波（CW）操作的热管理。进行热分析以计算具有散热的连续波操作下PCSEL的温度。我们将双晶格PCSEL组装在具有高导热底座的水冷包装中，以进行散热。我们使用热像仪测量设备温度，并将测量值与计算结果进行比较。由于适当的散热，我们成功地在单芯片双晶格PCSEL的CW操作下实现了$ {\ sim} {{8}} \; {\ rm {W}} $的输出功率。
