Room-temperature continuous-wave operation of all-AlGaAs visible (/spl sim/700 nm) vertical-cavity surface emitting lasers fabricated by selective oxidation

摘要

In summary, we have observed CW room temperature operation of 705.5 nm all-AlGaAs DBR QW VCSELs fabricated by selective oxidation. These devices, fabricated entirely with AlGaAs alloys, present an alternative material system for visible VCSELs.
