Failure Analysis of GaN-Based Current-Injected Vertical-Cavity Surface-Emitting Lasers

چکیده

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.

GaN-based VCSELs: Analysis of internal device physics and performance limitations

GaN-based vertical-cavity surface-emitting lasers (VCSELs) are expected to exhibit several advantages over their already widely used edge-emitting counterparts, including lower manufacturing costs, circular output beams, and longer lifetime. However, in contrast to the great success of GaN-based edge-emitting lasers in recent years, GaN-VCSELs still face significant challenges. Electrically pum...

On the importance of cavity-length and heat dissipation in GaN-based vertical-cavity surface-emitting lasers

Cavity-length dependence of the property of optically pumped GaN-based vertical-cavity surface-emitting lasers (VCSELs) with two dielectric distributed Bragg reflectors was investigated. The cavity lengths were well controlled by employing etching with inductively coupled plasma and chemical mechanical polishing. It was found that the lasing characteristics including threshold, slope efficiency...
