抄録

A LiNbO3 thin film was successfully fabricated onto a sapphire (001) substrate using pulsed laser deposition. The film quality was largely affected by substrate temperature, oxygen gas pressure, laser fluence and laser repetition frequency. By adjusting these conditions, a highly c-axis oriented LiNbO3 film was obtained. The ordinary refractive index of the film became 2.28 at 632.8 nm of wavelength, which coincided with that of a LiNbO3 single crystal. RHEED observation showed the film had twin boundaries. Further improvements are now undergoing.
