Abstract
An electrically pumped optical device includes a semiconductor active region and a backward diode. Both of these structures are located in the current path of the optical device, which is oriented primarily vertically. The active region has a finite extent along at least one lateral dimension. The overall structure improves the electrical performance of the device.
