Abstract :
We report the first antireflection coatings for fibre pigtailed Ti:LiNbO3 waveguide devices optimised for the 1.55 ¿m wavelength range. The coatings are single-layer, electron-beam-evaporated yttrium oxide films. A reflection of ¿35 dB, sufficiently low for operation in conjunction with single-frequency lasers, has been demonstrated.
