A silicon photonics modulator includes a substrate, a PN junction disposed on the substrate, the PN junction formed by a first L-shaped region doped with a p-type doping abutting a second L-shaped region doped with an n-type doping, a first plurality of regions each having different p-type doping concentrations greater than the first L-shaped region, and a second plurality of regions each having different n-type doping concentrations greater than the second L-shaped region. The silicon photonics modulator includes a first electrical contact on one of the first plurality of regions, a second electrical contact on one of the second plurality of regions, and multiple grating pillars doped with the n-type doping or the p-type doping, each of the multiple grating pillars spaced apart from the PN junction and spaced apart from one another.
