Abstract :
Summary form only given. The authors report 1.5 μm GaInAs/AlGaInAs GRIN-SCH SL (strained layer) QW (quantum well) LDs (laser diodes) having both compressive and tensile strain in the well. They were grown by low-pressure organometallic chemical vapor deposition (OMCVD). Very low threshold current densities of 200 and 400 A/cm2 were obtained in tensile and compressive SL QW LDs, respectively. The characteristic temperatures were 60 K for a lattice-matched QW LD, 72 K for a compressive SL QW LD, and 50 K for a tensile SL QW LD. Lasing wavelengths were in the 1.5 μm range for all cases
