ECOC2024：华为之量子点激光器ECOC2024: Huawei's Quantum Dot Laser
<p>➀ 华为在（100）硅衬底上单片生长单模FP量子点激光器，其光功率在25℃ 120mA时达到33mW；</p><p>➁ 最终的LI曲线显示，在25℃和85℃的阈值分别为18 mA和30 mA，在85℃和300 mA时，出光功率达到70 mW，没有明显的rollover现象；</p><p>➂ 可靠性测试显示，在5000小时后阈值电流增加了6%，光功率衰减小于5%，在整个过程中没有观察到明显的退化趋势。</p><p>➀ Huawei has grown single-mode FP quantum dot lasers on (100) silicon substrates with a power of 33mW at 25℃ and 120mA;</p><p>➁ The final LI curve shows threshold currents of 18 mA and 30 mA at 25C and 85C, respectively, with an output power of 70 mW at 85℃ and 300 mA without any obvious rollover phenomenon;</p><p>➂ The reliability test shows that the threshold current increased by 6% after 5000 hours, and the light power decayed by less than 5%, with no significant degradation trend observed throughout the process.</p>
