Abstract:
1. An article of manufacture, comprising: at least one light emitting device located on a semiconductor wafer, wherein the light emitting device emits light substantially parallel to the plane of the wafer through one or both of a first end and a second end; and a test structure formed in the wafer and removable therefrom, the test structure being optically coupled to one of the first end or the second end of the light emitting device and comprising an inclined interface formed in the wafer between a first non-gaseous material and a second non-gaseous material, wherein the interface is capable of directing light received from the first end or the second end of the light emitting device towards a direction different from an original path of the light emitted from the first end or the second end of the light emitting device.
