Abstract
Lighting-emitting devices and more particularly light-emitting diode (LED) chips with multiple wavelength emissions and related methods are disclosed. LED chips include separately formed active LED structures that are bonded together to form a single LED chip capable of emitting multiple wavelengths. Each active LED structure may be separately patterned into a number of individual light-emitting junctions such that after bonding, a single LED chip includes multiple light-emitting junctions from multiple active LED structures. Patterns of individual light-emitting junctions may be selected so that when bonded together, emissions from different active LED structures may pass through LED chips with reduced interactions with one another. Certain aspects include vertical and horizontal offset positions for light-emitting junctions formed from different active LED structures.
