An optical modulator includes an input waveguide, a splitting point, a first interaction arm of length L1, a second interaction arm of length L2 that is unequal in length to the first interaction arm, a recombination point, and an output waveguide. The splitting point receives an incoming continuous wave light beam comprising two or more wavelengths of light from the input waveguide and splits it into a first light beam and a second light beam. The first interaction arm is coupled to the input waveguide and transports the first light beam. The second interaction arm is coupled to the input waveguide and transports the second light beam. The output waveguide is coupled to the first interaction arm and second interaction arm at the recombination point and combines the first light beam and second light beam into an output modulated light beam. The first interaction arm and the second interaction arm comprise an electro-optic material with a refractive index that changes according to a modulation stimulus. The electro-optic material has a first refractive index n1 before the modulation stimulus is applied, and a second refractive index n2 after the modulation stimulus is applied.
