We report the deposition, characterization, and application of novel optically transparent electrodes, namely ultrathin chromium films and amorphous carbon layers (a-C:H), suitable for replacing ITO and other common materials used so far in electro-optics. The ultrathin layers provide sufficient optical transmission of up to 95% for layer thicknesses of 2 nm and 5 nm for Cr and a-C:H, respectively, showing a flat spectral dependence between 400 and 800 nm. These features are maintained when using these coatings as electrodes on tapered optical fibers as used for scanning near-field optical microscopy (SNOM). We show the successful application of such coated optical tips for ferroelectric domain switching on the nanometer scale.
