Self-oscillations and dynamic behavior of aged InGaAsP laser diodes

The pulse response of vapor-phase grown InGaAsP/InP 1.3 μm laser diodes was studied before and after accelerated aging. Dynamic behavior, including self-sustained oscillations, was found to be largely unaffected by the aging process. This indicates that these lasers can be preselected for specified modulation characteristics that will remain constant over the operating life of the diode.
