Patent attributes
A semiconductor light-emitting device includes a junction between doped semiconductor layers, a first set of multiple independent contacts connected to a first doped layer and a second set of one or more contacts connected to the second doped layer. Multiple conductive vias connect the independent contacts to the first doped layer, enabling differing corresponding via currents to be applied to the first doped layer through the vias independent of one another. A spatial distribution of via currents among the multiple vias can be selected to yield a corresponding spatial distribution of emission intensity. Alteration of the via current distribution results in corresponding alteration of the emission intensity distribution; such alterations can be implemented dynamically. Multiple devices can be arranged as a light-emitting array.
