Abstract
An investigation of the micromachining of trenches in lithium niobate (LiNbO3) using direct imaged 248 nm KrF excimer laser ablation is presented. Trenches 20 μm wide and 0.5-7.5 μm deep have been produced. These trenches are assessed and are deemed suitable for the machining of integrated electro-optic structures. Based on the characterized ablation conditions, trenches of high quality have been successfully fabricated on an X-cut optical modulator which is potentially important for the realization of efficient broadband optical intensity modulators.
