Abstract
Vertical-cavity surface-emitting lasers (VCSELs) have been transferred from their original GaAs substrates to Cu substrates and continuous w ave operation has been obtained on the VCSELs after epitaxial transfer . The resultant measurements show a doubling of the output power and a 20% reduction in the thermal impedance, Increased optical power is ex plained by improved thermal heat sinking as measured from the lasing s pectra of horizontal-cavity edge-emitting lasers fabricated from the s ame VCSEL material.
