MULTI-JUNCTION OPTICAL EMITTER WITH MULTIPLE ACTIVE REGIONS ALIGNED TO MULTIPLE WAVELENGTHS

MULTI-JUNCTION OPTICAL EMITTER WITH MULTIPLE ACTIVE REGIONS ALIGNED TO MULTIPLE WAVELENGTHS

In some implementations, an optical emitter includes a set of light emitting junctions; and a set of tunnel junctions separating the set of light emitting junctions, wherein a first light emitting junction, of the set of light emitting junctions, is associated with a peak gain at a first wavelength,...

Zusammenfassung:In some implementations, an optical emitter includes a set of light emitting junctions; and a set of tunnel junctions separating the set of light emitting junctions, wherein a first light emitting junction, of the set of light emitting junctions, is associated with a peak gain at a first wavelength, and wherein a second light emitting junction, of the set of light emitting junctions, is associated with a peak gain at a second wavelength that is different from the first wavelength.
