We demonstrate that (1+1)-dimensional and (2+1)-dimensional waveguides can be induced by self-focused dark notches and crosses and stored in LiNbO3:Fe crystals. This is very valuable for information processing and integrated optics. The self-focused dark notches and crosses may be related to the formation of (1+1)-dimensional and (2+1)-dimensional photovoltaic dark spatial solitons in LiNbO3:Fe crystals.
