Light-current and derivative voltage-current characteristics are compared for dielectric-isolated stripe-geometry InGaAsP DH lasers operating under both pulsed and continuous excitation at wavelengths near 1.3 and 1.6 μm. At both wavelengths the lasers have comparable threshold temperature dependences, and both exhibit similar kinks and light jumps in their characteristics. The low T0values observed ( \sim50- 70 K) cannot be attributed to drift-current losses.
