Wavelength shifts of 1.5-/spl mu/m DFB lasers due to human-body-model electrostatic discharge followed by accelerated aging experiments

This paper reports human-body-model (HBM) electrostatic discharge (ESD)-induced wavelength shifts of 1.5 /spl mu/m InGaAsP/InP distributed feedback (DFB) lasers. Reverse-bias ESD has been exposed to the lasers. Their electrical and optical characteristics are significantly changed after ESD exposure. From most of ESD stressed lasers, the wavelength shifts are measured to be less than 2 /spl Aring/. Subsequent aging results show that the aging-induced wavelength shifts of ESD damaged lasers are less than 0.5 /spl Aring/. No significant impact on reliability has been found from ESD damaged lasers. Similar results are obtained from non-ESD damaged lasers except for the shift direction of the lasing wavelengths.<
