The basic physics of nonlinear optics in semiconductors is reviewed. Optical bistability due to increasing absorption and in a Kerr cavity is discussed, as are spatial solitons in a Kerr medium. These introduce recent research on spontaneous pattern

A numerical study of continuous-wave and pulse propagation in three-core fibre nonlinear directional couplers is presented. Intensity dependent demultiplexing is illustrated; in particular, novel nonlinear behaviour where a very small change in peak

We present a general form of master equation for nonlinear-optical cavities that can be described by an ABCD matrix. It includes as special cases some previous models of spatiotemporal effects in lasers.

Studies of the angular dependence of cw degenerate four-wave mixing in n-type InSb have yielded a value for the diffusion length, l(D), of 60 +/- 2 microm. From this, the dependence of l(D) on photoexcited carrier concentration is calculated. A simpl

A model which supports grating-controlled transverse traveling wave modes in VCSELs with an external cavity is developed. An annular spatial filter is introduced into the external cavity to control the dynamical complexity of the system. This work sh

Spatial solitons in cavities are being investigated with a view to applications in parallel information processing [1]. Such arrays offer functionalities which are beyond any micro-structured material array, whether optical or electronic. This paper

Hexagons and other regular patterns are predicted in a number of wide-aspect nonlinear optical systems. Analysis and simulations of pattern formation in two classes of systems are presented. These are feedback systems, in which the mechanism is relat
