achievements in the field of soliton lattices and discrete soliton observation
obtained in photorefractive SBN [172, 173, 174, 175, 176, 177], and in the
trapping of more exotic excitations such as rings [178].
Although we have attempted to give a detailed account of all aspects
of photorefractive self-trapping, the field has undergone such a rapid and
extensive evolution that we can hardly guarantee that all contributions have
been cited and described. Perhaps this is yet another accomplishment of
photorefraction, that is, having given to the soliton science community a
powerful and accessible tool with which to further its research and develop
new and possibly useful scientific and practical tools.
13 Dedication
Moti Segev would like to dedicate this Chapter to his friend Galit Staier, who
was critically wounded in the murderous Palestinian suicide attack on October
4, 2003, in the Maxim restaurant in Haifa, Israel. In that suicide bomb a
Palestinian woman blew herself up killing 21 civilians. Galit has has lost her
11-year old son Assaf Staier, her father Ze’ev Almog (71), her mother Ruth
