<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>
