Abstract: 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.

Abstract: A vertical cavity surface emitting laser (VCSEL) array may include a plurality of VCSELs. A size of an emission area of a first VCSEL, of the plurality of VCSELs, may be different from a size of an emission area of a second VCSEL of the plurality of VCSELs. The first VCSEL may be located closer to a center of the VCSEL array than the second VCSEL. A difference between the size of the emission area of the first VCSEL and the size of the emission area of the second VCSEL may be associated with reducing a difference in operating temperature between the first VCSEL and the second VCSEL, or reducing a difference in optical power output between the first VCSEL and the second VCSEL.

Abstract: A method for fabricating an array of emitters may include providing a first metallization layer for a first set of emitters of a first channel, wherein the first metallization layer comprises a first interchannel portion positioned between the first set of emitters and a second set of emitters of a second channel. The method may include depositing a dielectric layer on the first interchannel portion of the first metallization layer. The method may include providing a second metallization layer for the second set of emitters, wherein the second metallization layer comprises a second interchannel portion positioned between the first set of emitters and the second set of emitters, and wherein the second interchannel portion of the second metallization layer at least partially overlaps the first interchannel portion of the first metallization layer.

Abstract: An emitter array may comprise a plurality of emitters and a metallization layer to electrically connect the plurality of emitters. The metallization layer may have a first end and a second end. The plurality of emitters may include a first emitter and a second emitter. The first emitter may be located closer to the first end than the second emitter. The first emitter and the second emitter have differently sized structures to compensate for a first impedance of the metallization layer between the first end and the first emitter and a second impedance between the first end and the second emitter.
