A method and system for fabricating an optical component are described. The method and system include providing a first planarization stopping and a second planarization stopping structure. The first planarization stopping structure has a first height and a first edge. The second planarization stopping structure has a second height different from the first height and a second edge. The first edge is separated from the second edge by a distance. The method and system also include providing an optical material. The optical material resides at least between the first edge of the first planarization stopping structure and the second edge of the second planarization stopping structure. The method and system also include planarizing the optical components. The planarization removes a portion of the optical material to form a surface between the first planarization stopping structure and the second planarization stopping structure. This surface has a curvature.
