Hybrid plasmonic electro-absorption modulators

Abstract

Structures for an electro-absorption modulator and methods of forming a structure for an electro-absorption modulator. The structure comprises a first metal layer and a second metal layer adjacent to the multiple-layer structure, a waveguide core, and a multiple-layer structure on a portion of the waveguide core. The multiple-layer structure comprises a first plurality of layers and a second plurality of layers that alternate with the first plurality of layers. The first plurality of layers comprise a first material, and the second plurality of layers comprise a second material. The multiple-layer structure is positioned in a lateral direction between the first metal layer and the second metal layer.
