Abstract
We present highly reliable InAs/GaAs quantum dot lasers directly grown on CMOS compatible Si (001) substrate without any predefined pattern or intermediate material. Under 300mA driving current, the continuous wave optical power reaches 91mW and 70mW at 25 °C and 85 °C, respectively, with no obvious thermal rollover. Whilst operating at 85°C 100mA, the lasers have demonstrated lifetime beyond 3000 hours and the observed optical power deterioration is less than 5%.
