If the maximum modulation bandwidth of an electro-optic modulator is given

By

where λ0 denotes the wavelength in air, ε is the permittivity of the material, A

the cross-sectional area, L the optical path length in modulator, n the index of

refraction of material, r the appropriate element of the E-O tensor, and tg the

waveguide thickness.
