Abstract
A layout for a vertical-cavity surface-emitting laser (VCSEL) is provided. In an example embodiment, the layout comprises a VCSEL, an etched shape around a mesa of the VCSEL, a signal contact layer deposited on section of the mesa, and a ground contact layer. The ground contact layer comprises three parts and is positioned around a first section of the etched shape. The first part of the ground contact layer is deposited on a second section of the etched shape. The second and third parts of the ground contact layer comprise two legs off of the first part. The two legs are symmetrically positioned about two sides of the signal contact layer to form a ground-signal-ground configuration.
