Abstract
The technique of electric derivative measurement can be used for the simple screening of quickly degraded semiconductor lasers. The peaks in electric derivative (I dV/dI - I) and optic derivative curves (dP/dI - I) of GaAs/Ca AlAs high-power QW lasers have been investigated. The presence of peaks was used to judge the reliability and quality of devices. (C) 2000 Elsevier Sc ience Ltd. All rights reserved.
