heal.abstract	Optical spatio-temporal X-wave-like pattern formation is investigated in a voltage-controlled array of channel waveguides in nematic liquid crystals and in generic optically dispersive nonlocal nonlinear media as well. The nonlinear response of the system is governed by the spatio-temporal diffusion equation for the medium's response to the optical field, while the respective equation for the evolving light pulse may incorporate normal temporal dispersion. The associated discrete nonlinear Schrödinger equation which governs the evolution of the temporal profiles of a discrete set of modes is derived and is studied numerically. The results are obtained via full numerical investigation of the array with beam propagation techniques.	en
