The procedure of self-consistent calculation of excitonic states in T-shaped quantum wires is developed. The part of the exciton wave function describing an electron motion in the plane perpendicular to the wire direction and a term describing motion of a hole and the relative electron-hole motion i
Nonlinear light scattering and four-wave mixing from N interacting quantum wires are calculated using Green function techniques. Size confinement results in discrete single-and two-photon resonances. The nonlinear signal per wire increases with N for small N, and saturates at large N. Effects of int
