Spin casting electro-optic polymers for in-fiber device fabrication is problematic due to the flexibility and high-contrast topography of optical fibers. An ink-jetting method is developed for the deposition of AJL8/APC using a commercially available printer. The method results in more consistent control of film thickness and uses 1000 times less material than the spin-coating method. A D-fiber electric field sensor is fabricated using this deposition method and exhibits a sensitivity of 157 V/(m square root(Hz)) at a modulation frequency of 6 GHz.
