The propagation of light in dispersive media is a subject of
fundamental as well as practical importance. In recent years
attention has focused in particular on how refractive index can
vary with frequency in such a way that the group velocities of
optical pulses can be much greater or much smaller than the speed
of light in vacuum, or in which the refractive index can be
negative. Treating these topics at an introductory to intermediate
level, Fast Light, Slow Light and Left-Handed Light focuses on the
basic theory and describes the significant experimental progress
made during the past decade. The book pays considerable attention
to the fact that superluminal group velocities are not in conflict
with special relativity and to the role of quantum effects in
preventing superluminal communication and violations of Einstein
causality. It also explores some of the basic physics at the
opposite extreme of very slow group velocities as well as stopped
and regenerated light, including the concepts of
electromagnetically induced transparency and dark-state polaritons.
Another very active aspect of the subject discussed concerns the
possibility of designing metamaterials in which the refractive
index can be negative and propagating light is left-handed in the
sense that the phase and group velocities are in opposite
directions. The last two chapters are an introduction to some of
the basic theory and consequences of negative refractive index,
with emphasis on the seminal work carried out since 2000. The
possibility that "perfect" lenses can be made from negative-index
metamaterials-which has been perhaps the most controversial aspect
of the field-is introduced and discussed in some detail.
