Abstract

An optical modulator comprises a substratehaving a thickness of 20 μm or less and an electro-optic effect, a reinforcing substrateholding the substratethereon and a resin layerdisposed between the substrate and the reinforcing substrate, in which the substrateincludes optical waveguidesandand control electrodesandwhich control light waves propagating through the optical waveguide, in which the optical waveguides include at least two optical waveguidesseparated from each other, and in which the control electrodesdisposed between the two optical waveguides are configured to include two electrodesdisposed along each optical waveguide, and a thin lineconducting the two electrodesat a same potential.
