Abstract

Focussed ion beam micromachining is a new maskless process that may be used to fabricate deep (>10 µm) features in LiNb03. This is advantageous, because LiNb03 is difficult to etch selectively otherwise. Features in the form of trenches, cut accurately orthogonal to titanium-diffused channel waveguides, may be used as rugged on-chip mirrors for channel waveguide integrated optics. These may be combined with other waveguide components to form direct reflectors, reflective bends, and electro-optically switchable track-changing reflectors. Experimental data on all three devices are given.
