| Abstract: | A p-type superlattice is used to laterally inject holes into an
III-nitride multiple quantum well active layer, enabling efficient light
extraction from the active area. Laterally-injected light-emitting diodes
and laser diodes can enable brighter, more efficient devices that impact
a wide range of wavelengths and applications. For UV wavelengths,
applications include fluorescence-based biological sensing, epoxy curing,
and water purification. For visible devices, applications include solid
state lighting and projection systems. |
