Abstract :
A very low threshold current density of 400 A/cm2 was obtained in a 1.5 mu m GaInAs/AlGaInAs compressive strained-layer quantum well laser diode, grown by metal organic chemical vapour deposition (MOCVD), with continuously graded-index separate-confinement-heterostructure. A very low threshold current of 3.6 mA was achieved in a high reflective coated 130 mu m long buried heterostructure laser diode with MOCVD grown semi-insulating current blocking layer. The lasing wavelength was 1.48 mu m.
