A spatial light modulator includes a semiconductor substrate and a plurality of micro-mirrors arranged on the semiconductor substrate to modulate light. Each of the micro-mirrors has a center and a perimeter. Each of the micro-mirrors includes a layer of a reflective material arranged on the semiconductor substrate. In in each of the micro-mirrors, the layer of the reflective material extends horizontally from the center towards the perimeter for a predetermined distance and slopes downwards towards the semiconductor substrate after the predetermined distance.
