On the efficient coupling of optical fiber and channel waveguides

The coupling of optical fibers and channel waveguides has been important and difficult problem in integrated optics. It is, too, the only way for integrated optics from experiment approaching to its application. Here we report two parts of our works, namely, on the end fire coupling between single-mode optical fibers and Ti-diffused LiNbO3 channel waveguides.
