Abstract :
Transmission characteristics of gamma-irradiated LiNbO3 waveguides, made by five different methods, are measured and studied. All samples were irradiated with a dosage of 800 krad/h to a total amount of 10 Mrad. With the increasing gamma-irradiation intensity, the annealed proton-exchange waveguide shows the most anti-irradiative ability and the lowest transmission loss, where the measurements were carried out at a wavelength of 633 nm in a harsh gamma-irradiative environment.
