本文从理论上研究了超低功耗薄膜分布反馈激光器中电流注入引起的自热效应。通过对其温度分布的模拟，估计出激光器的热阻为6100 K/W。此外，还计算了自热效应对激光特性的影响。0.18兆瓦的输出功率——对于片上光源来说是足够的——可以在1兆瓦的驱动功率下获得。我们证明了由于薄膜激光器的超低阈值工作，自热效应对薄膜激光器的激光特性影响很小。
We theoretically investigated the self-heating effect caused by current injection into a membrane distributed feedback laser designed to operate at ultralow-power consumption. By simulating its temperature distribution, the thermal resistance of the laser was estimated to be 6100 K/W. In addition, changes in lasing characteristics owing to the self-heating effect were calculated. An output power of 0.18 mW - which is adequate for an on-chip light source - can be obtained at a driving power of 1 mW. We proved that, owing to its ultralow-threshold operation, the self-heating effect has little effect on the lasing characteristics of the membrane laser.
