Vertical-cavity surface-emitting lasers (VCSELs) with oxide layers introduced for modal property control are relatively weak against reliability-related damage. We propose and demonstrate a method of detecting potential damage without running a long-

Electrostatic discharge(ESD) damage is known as a major source affecting the lifetime of oxide VCSEL. We investigated how ESD damage threshold voltage depends on the size, thickness, and composition of the oxide aperture by measuring the change of ou
