Reconfigurable integrated optical microswitch device

A switching method of an optical signal, comprising:

• arranging a substrate of electro-optical material comprising an array of waveguides, a first and a second layer of driving electrodes connected to the waveguides, and a layer of dielectric insulating material arranged between the layer of electro-optical material and at least the first or the second layer of driving electrodes, wherein the layer of electro-optical material comprises an upper planar surface, and wherein the waveguides are arranged, adjacent to each other and distanced from one another, at the upper planar surface of the layer of electro-optical material, each one of these waveguides comprising an input end, an output end, at least two side walls, and an upper wall,
• simultaneously distributing an optical signal through said array of waveguides;
• and
• predetermining and applying an electrical potential value on each waveguide for modifying the respective refraction index, thereby generating a plurality of individual wave fronts that are offset from each other according to a first predetermined configuration.
