Abstract :
Continuous wave room-temperature output power of ∼3 W for edge-emitters and of 0.8 mW for vertical-cavity surface-emitting lasers is realized for GaAs-based devices using InAs quantum dots (QDs) operating at 1.3 μm. Long operation lifetimes and radiation hardness are manifested and cut-off frequency of about 10 GHz is realized. The breakthrough became possible due to development for self-organized growth in QD technology.
