Paper Abstract

Light-current, relative intensity noise and spectral characteristics of a group of gain-guided InGaAsP/InP MQW buried heterostructure laser diodes have been investigated under accelerated aging conditions. The operating current, Iop, at constant output optical power increases logarithmically with time in stable devices, which indicates that the life expectancy of the lasers exceeds 2x105 hours or greater than 20 years. The emitted light wavelength at constant output power shifts by 2-2.5Å during 3000 hours of overstressing, mainly due to the increase in Iop. High-frequency RF signal-induced transient chirp for relative stable LDs at constant output power shows very little change with time.
