Abstract :
High-quality 1.3 (mu)m GaInNAs/GaNAs single quantum well lasers grown by molecular beam epitaxy are reported. The broad area lasers show a record low threshold current density of 318 A/cm/sup 2/ for a cavity length of 1 mm, a transparent current density of 84 A/cm/sup 2/, and a characteristic temperature of 103 K from 8 to 70(degree)C.
