There is an error in Figure 1(e) of the original article.1 The white arrow indicating the direction of the spontaneous polarization in the poling inhibited domain should point upwards. The correct figure is shown below.

FIG. 1.

Processes involved in the production of a channel waveguide overlapping a PI domain (the arrows indicate the direction of spontaneous polarization, Ps, in each section): (a) UV-irradiation of the +z face and formation of temperature gradient (red region), (b) lithium ion re-distribution, (c) refractive index (ne) profile corresponding to lithium distribution profile, (d) coercive field profile corresponding to lithium distribution profile, and (e) resulting waveguide/domain composite. The lateral distribution curves for temperature, lithium concentration, refractive index, and coercive field that appear on top of each image are for illustration purpose only and are not accurate.
