Abstract: In this contribution we demonstrate an all-organic Mach-Zehnder interferometric electro-optic waveguide modulator capable of operating in the visible and infrared spectral range. We demonstrate experimentally an operation of modulator design that comprises SU-8 as waveguide core and an electro-optic host-guest glass forming polymer as a cladding. The modulator is tested in the visible part of the spectral range and the results indicated comparatively high efficiency in-device in-plane poling (up to 30 %) of the value reached in thin films.


Keywords: Integrated optics devices, Modulators, Electro-optic polymer, Waveguide Mach-Zehnder.
