Abstract
Sustained oscillations in proton‐bombardment‐delineated stripe‐geometry (Al,Ga)As double‐heterostructure injection lasers are shown to be adversely influenced (enhanced) by the presence of dc current bias in the devices. The time constant for this enhancement is found to be in the range 2–5 μsec and is interpreted as being thermal in origin. A previously proposed saturable absorber model of pulsations is qualitatively consistent with these results.Keywords
