Abstract
An optical modulator comprises a silicon substrate, a buried oxide (BOX) layer disposed on top of the silicon substrate, and a ridge waveguide disposed on top of the BOX layer and comprising a first n-type silicon (n-Si) slab, a first gate oxide layer coupled to the first n-Si slab, a first p-type silicon (p-Si) slab coupled to the first gate oxide layer, and a light propagation path that travels sequentially through the first n-Si slab, the first gate oxide layer, and the first p-Si slab.
