Abstract :
Recent data on two approaches for 1.3 μ laser operation on GaAs substrates, InAs QDs and InGaNAs QWs, are presented. Lasers fabricated with epitaxial films of MBE grown InAs/InGaAs quantum dots have shown to be capable of ultra low threshold current operation near 1 mA while reaching several mW power level. MOCVD grown InGaNAs quantum wells showed low threshold density of less than 400 A/cm2.
