ABSTRACT:
A vertical cavity surface emitting laser is provided with a mode control structure that selectively encourages or inhibits the lasing of the laser in regions of the mode control structure. Light is encouraged to lase and emit light through first portions of the mode control structure while lasing is inhibited in second portions. The first and second portions of the mode control structure are patterned by providing different thicknesses for the first and second portions of the mode control structure.
