Abstract :
This paper reports human-body-model (HBM) electrostatic discharge (ESD)-induced wavelength shifts of 1.5 μm 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 Å. Subsequent aging results show that the aging-induced wavelength shifts of ESD damaged lasers are less than 0.5 Å. 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
