More Information
Summary:Provided is an optical modulator. The optical modulator includes an optical waveguide device and an electrochromic device on the optical waveguide device. The optical waveguide device includes a cladding layer and a core layer extending in a first direction on the cladding layer. The electrochromic device includes a lower electrode on the core layer, an upper electrode facing the lower electrode, an electrolyte layer between the lower electrode and the upper electrode, and an electrochromic layer between the lower electrode and the electrolyte layer.
