This paper presents the recent topics of the laser-beam (LB) writing techniques for fabrication of integrated-optic devices in Ti:LiNbO3 in addition to the practical LB writing system for channel waveguide patterning in photoresist. Recently, the direct LB writing of TiO2 channels on LiNbO3 was demonstrated, providing the photoresist-free process for fabrication of Ti:LiNbO3 waveguides with higher accuracy and reproducibility. Besides the channel waveguide patterning, the interdigital electrodes required for TE-TM mode conversion in Ti:LiNbO3 waveguide wavelength filters can be defined with an accuracy of the order of nanometer by a unique LB writing technique that is the so-called LB periodic-dot writing. The writing accuracy is discussed in detail as well as the performance of the fabricated filter.
