Intermodulation distortion in high dynamic range microwave fiber-optic links with linearized modulators [PDF]
, 1993 Linearization of integrated optic intensity modulators significantly reduces the two-tone intermodulation distortion. The resulting intermodulation distortion produced by these modulators then varies as the input power to the fifth-order link system, the
