An Atlas of ESD Failure Signatures in Vertical Cavity Surface Emitting Lasers
ثبت نشده
چکیده
AOC herein describes a collection of material degradation features observed in Vertical Cavity Surface Emitting Lasers (VCSELs) that have been intentionally degraded with a range of electrostatic discharge (ESD) stress conditions. Failure analysis techniques employed include emission microscopy, Focused Ion Beam (FIB) microscopy and Transmission Electron Microscopy (TEM). The results have enabled higher confidence in root-cause determination for failed VCSEL devices.

متن کاملObservation of low-frequency fluctuations in vertical-cavity surface-emitting lasers.
Low-frequency fluctuations, which are typical irregular oscillations in edge-emitting semiconductor lasers, are experimentally observed for the y-polarization mode (y is the direction along the optical axis of a laser material) in a vertical-cavity surface-emitting laser with optical feedback.
متن کاملFailure Analysis of GaN-Based Current-Injected Vertical-Cavity Surface-Emitting Lasers
This paper investigates internal physical mechanisms that have thus far prevented current-injected InGaN/GaN verticalcavity surface-emitting lasers (VCSELs) from lasing. Advanced device simulation is applied to a realistic VCSEL design. Several obstacles to lasing are identified, including current leakage, lateral carrier non-uniformity, and selfheating during pulsed operation.
