Claim 10:
11. An optical modulator apparatus, comprising:
a first dielectric layer over a substrate;
a rib waveguide comprising a PN junction on the first dielectric layer, the PN junction of the rib waveguide comprising a P-doped region adjacent an N-doped region;
a first slab region adjacent to the P-doped region and a second slab region adjacent to the N-doped region;
a second dielectric layer over the rib waveguide; and
a stressor layer comprising a metal, wherein the first dielectric layer is between the stressor layer and the PN junction, and wherein the stressor layer is below the PN junction by a distance substantially equal to a thickness of the first dielectric layer.
