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.
Claims20
A vertical cavity surface emitting laser (VCSEL) array, comprising:
- a plurality of VCSELs;
- and
- a metallization layer to electrically connect the plurality of VCSELs,
- wherein the metallization layer has a first end and a second end,
- wherein the plurality of VCSELs includes a first VCSEL and a second VCSEL,
- wherein the first VCSEL is located closer to the first end than the second VCSEL,
- wherein a first structure of the first VCSEL is different than a second structure of the second VCSEL in accordance with a difference in a first electrical impedance of the first VCSEL and a second electrical impedance of the second VCSEL when the metallization layer is powered.
An emitter array, comprising:
- a plurality of emitters;
- and
- a metallization layer to electrically connect the plurality of emitters,
- wherein the metallization layer has a first end and a second end,
- wherein the plurality of emitters includes a first emitter and a second emitter,
- wherein the first emitter is located closer to the first end than the second emitter,
- wherein 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.
A laser array, comprising:
- a plurality of laser devices;
- and
- a metallization layer to electrically connect the plurality of laser devices,
- wherein the metallization layer has a first end and a second end,
- wherein the plurality of laser devices includes a first laser device and a second laser device,
- wherein the first laser device is located closer to the first end than the second laser device,
- wherein the first laser device and the second laser device have different structures that are configured such that a difference between a first input power to the first laser device and a second input power to the second laser device satisfies a threshold.
