 appeared in 1995 several reprints became necessary starting from 1997, one
 of them for the Chinese market. They contained only rather limited updates
 of the material and corrections.
 In the meantime scientific progress brought a lot of new results, which
 necessitate a new, seriously revised edition. This progress includes bulk semi-
 conductors, but especially structures of reduced dimensionality. These new
 trends and results are partly included in existing chapters e.g. for phonons or
 for time-resolved spectroscopy, partly new chapters have been introduced like
 the ones on cavity polaritons and photonic structures.
 We based the description of the optical properties again on the simple and
 intuitively clear model of the Lorentz-oscillators and the concept of polaritons
 as the quanta of light in matter. But since there is presently a trend to describe
 at least the optical properties of the electronic system of semiconductors by
 the optical or the semiconductor Bloch equations, a chapter has been added
 on this topic written by Prof. Dr. R. v. Baltz (Karlsruhe) to familiarize the
 reader with this concept, too, which needs a bit more quantum mechanics
 compared the approach used here. The chapter on group theory has been
 revised by Prof.Dr. K. H¨ ummer (Karlsruhe/Forchheim)
