Abstract
An optical modulator includes a slab of silicon, a first layer of silicon disposed on the slab, and a second layer. The second layer includes a mixture of germanium and silicon. The second layer is at least partially disposed on the first layer. The second layer includes an intrinsic portion of the mixture and further includes first and second doped portions disposed on opposite sides of the intrinsic portion. The intrinsic portion and the first and second doped portions form an active region of the optical modulator.
