Abstract
Various embodiments of the present disclosure are directed towards a vertical cavity surface emitting laser (VCSEL) device. The VCSEL device includes a bond bump overlying a substrate. A VCSEL structure overlies the bond bump. The VCSEL structure includes a second reflector overlying an optically active region and a first reflector underlying the optically active region. A bond ring overlying the substrate and laterally separated from the bond bump. The bond ring continuously extends around the bond bump.
