Digitally Chirped Multilayer Quantum Dot Lasers with Dual-Wavelength Lasing Emissions
The dual-wavelength lasing emissions of digitally chirped multilayer quantum dot (QD) lasers are investigated both experimentally and theoretically. The two lasing wavelengths are both identified as ground-state (GS) emissions but originated from different stacks of QD multilayers. The lasing spectr...
