Notes:
Solid-source molecular beam epitaxy with substrate temperature modulation has produced periodic index separate confinement heterostructure InGaAs/AlGaAs quantum well lasers with greatly improved performance. These lasers in a broad area geometry are under room-temperature continuous wave operation and have low threshold current density of 300 A/cm2, high internal quantum efficiency of 91%, low internal waveguide loss of 2.2 cm−1, a reduced transverse beam divergence of 30°, and a high characteristic temperature of 187 K.
