“…Jiao et al demonstrated the optical channel WG in x-cut KTiOAsO 4 crystal produced by photo masking and following direct O + ion implantation at an energy of 3.0 MeV and fluence of 5 × 10 13 ions/cm 2 . The propagation losses of the WG are 1.2 dB/cm, which displays satisfactory guiding characteristics [146]. Schematic illustration of the channel WG manufacturing procedure via ion-implantation is shown in Figure 6.…”

In the past few decades, several methods concerning optical thin films have been established to facilitate the development of integrated optics. This paper provides a brief depiction of different techniques for implementing optical waveguide thin films that involve chemical, physical, and refractive index modification methods. Recent advances in these fabrication methods are also been presented. Most of the methods developed for the realization of the thin-films are quite efficient, but they are expensive and require sophisticated equipment. The major interest of the scientists is to develop simple and cost-effective methods for mass production of optical thin films resulting in the effective commercialization of the waveguide technology. Our research group is focused on developing a silica-titania optical waveguide platform via the sol-gel dip-coating method and implementing active and passive optical elements via the wet etching method. We are also exploring the possibility of using nanoimprint lithography (NIL) for patterning these films so that the fabrication process is efficient and economical. The recent developments of this platform are discussed. We believe that silica-titania waveguide technology developed via the sol-gel dip-coating method is highly attractive and economical, such that it can be commercialized for applications such as sensing and optical interconnects.

“…), surface patterning technologies are necessary to be incorporated. Such technologies contain lithography, chemical etching, diamond blade dicing and laser ablation [26]- [28]. Ultrafast laser ablation has been proven to be a feasible and simple method to manufacture ridged guiding structures in several optical materials, including single crystals and glasses [29]- [32].…”

We report on the fabrication of ridge waveguides and Y-branch beam splitters in KTiOAsO 4 nonlinear optical crystal by the combination of 15 MeV oxygen (O 5+ ) ion implantation and femtosecond laser ablation. Guiding properties were investigated at the wavelengths of 633 and 808 nm, respectively, showing high polarization sensitivity of light propagation. Splitting ratios of these beam splitters are dependent on in-coupling alignment. The simulated guiding modal distributions of splitted guided beams, which was based on a reconstructed refractive index profile, shows reasonable consistence with the measured ones. After the stepwise annealing treatment at 473 and 573 K for 1 h each, the propagation losses for these guiding structures have been reduced considerably.
