1. A system comprising:
- a light emitting device including;
a multi-layer stack of materials including a light generating region, and a first layer supported by the light generating region, a surface of the first layer being configured so that light generated by the light generating region can emerge from the light emitting device via a surface of the first layer, a shape of a surface of the multi-layer stack being rectangular and the surface of the first layer having a dielectric function that varies spatially according to a pattern; and
at least one electrical contact pad disposed along an edge of the surface of the first layer; and
a package having a first surface and a second surface opposite the first surface, the package including;
a plurality of plated regions for providing electrical contact to the light emitting device; and
a plurality of wire bonds connected between the plated regions and the at least one electrical contact pad.
