Abstract:
Solid state lighting devices that can produce white light without a phosphor are disclosed herein. In one embodiment, a solid state lighting device includes a first semiconductor material, a second semiconductor material spaced apart from the first semiconductor material, and an active region between the first and second semiconductor materials. The active region includes a first sub-region having a first center wavelength and a second sub-region having a second center wavelength different from the first center wavelength.
