More Information
Summary:A surface emitting laser may include an isolation layer including a first center portion and a first plurality of outer portions extending from the first center portion, and a metal layer including a second center portion and a second plurality of outer portions extending from the second center portion. The metal layer may be formed on the isolation layer such that a first outer portion, of the second plurality of outer portions, is formed over one of the first plurality of outer portions. The surface emitting laser may include a passivation layer including a plurality of openings. An opening may be formed over the first outer portion. The surface emitting laser may include a plurality of oxidation trenches. An oxidation trench may be positioned at least partially between the first outer portion and a second outer portion of the second plurality of outer portions.
