A study of pulsations, superlinear emission, and negative resistance in 1.3 µm InGaAsP double-heterostructure lasers

Self-sustained pulsations, superlinear emission, and negative-resistance behavior of several 1.3μm InGaAsP stripe-geometry double-heterostrueture lasers are studied as a function of temperature and drive current. The pulsations are observed in a certain current range above threshold. This current range increases with increasing temperature. Also, the… (More)
