Due to its immediate response, the electro-optic effect is exploited for high-frequency phase and power modulation and for beam deflection. Besides the immediate response, electro-optic materials exhibit creep due to relaxation processes in the material, which results in a gradual settling of the response when a voltage is applied for tens of milliseconds. A bi-exponential filter can compensate this behavior, reported here for electro-optic deflectors made of AD*P, such that these deflectors can be used over the entire frequency range of the driver with a residual settling error <0.001 of the deflection.
