T. Egawa et al., LOW-TEMPERATURE CONTINUOUS-WAVE OPERATION OF ALGAAS-GAAS VERTICAL-CAVITY SURFACE-EMITTING LASERS ON SI SUBSTRATES, IEEE photonics technology letters, 9(7), 1997, pp. 872-874
An AlGaAs-GaAs multiquantum-well vertical-cavity surface-emitting lase
r (VCSEL) diode has been grown on a Si substrate using metalorganic ch
emical vapor deposition. The VCSEL structure grown on a Si substrate c
onsists of ten quantum well active layers and a 23-pair of AlAs-Al-0.1
Ga0.9As distributed Bragg reflector. The VCSEL on a Si substrate exhi
bited a threshold current of 82 mA and a threshold current density of
4.2 kA/cm(2) under continuous-wave (CW) condition at 150 K. Electrolum
inescence observation showed that optical degradation is caused by the
generation and growth of dark-line defects.
