Abstract
A silicon-based electro-optic modulator includes a substrate layer, an insulation layer, and an optical waveguide layer stacked sequentially, traveling wave electrodes disposed above the optical waveguide layer, and a metal grating structure periodically configured along the direction in which an electrical signal propagates in the traveling wave electrodes. The metal grating structure is disposed above the optical waveguide layer.
