Abstract
A planar array of vertical-cavity, surface-emitting diode lasers, and its method of making. The device comprises an active region having a quantum well region disposed between two Bragg reflector mirrors separated by a wavelength of the emitting laser. A large area of this structure is grown on a substrate and then laterally defined by implanting conductivity-reducing ions into the upper mirror in areas around the lasers. Thereby, the laterally defined laser array remains planar. Such an array can be made matrix-addressable by growing the structure on a conducting layer overlying an insulating substrate. After growth of the vertical structure, an etch or further implantation divides the conducting layer into strips forming bottom column electrodes. Top row electrodes are deposited in the perpendicular direction over the laterally defined top mirrors.
