Radiation damage of titanium diffused lithium niobate devices.
05 January 1990
The damage due to ionizing radiation on titanium diffused lithium niobate waveguide devices is investigated. Several waveguide devices containing straights, bends, and directional couplers are irradiated with both gamma radiation and high energy electrons. Passive optical measurements as well as in-situ measurements are performed on the exposed waveguide devices. It was found that the waveguide devices were hard to gamma radiation at doses up to 10 sup 7 rads. Also the waveguide devices showed small permanent changes to high doses (3300 Mrads) of electron radiation.
