We combine substrate-free dielectric thin-film elements, spin coated electro-optically (EO) active polymers and transparent electrical contacts into an actively switchable Fabry-Pérot modulator design for the 950 nm– 1064nm wavelength region. Aligned integration of the modulator into a microoptic chip is realized with a precision optics assembly system. High integration densities can be achieved since the estimated total width of the modulator along the optical axis amounts only to a few tens of micrometers.
