Electro-optic modulator includes a substrate, a waveguide formed in a top surface of the substrate, first modulating electrodes and second modulating electrodes. The waveguide includes a Y-shaped incident member, a Y-shaped output member, and first and second connection members. The Y-shaped incident member includes an incident portion, first and second incident branches. The Y-shaped output member includes an output portion, a first and second output branches. The first connection member includes a first branch and a second branch. The second connection member includes a third branch and a fourth branch. The first branch and the second branch are interconnected between the first incident branch and the first output branch and arranged in parallel. The third branch and the fourth branch are interconnected between the second incident branch and the second output branch and arranged in parallel. |
