    Based on Fermat's principle, geometrical optics offers a simplified understanding of optical systems.
    FIGURE 1. A 1 x 1 optical switch can be created from a Mach-Zehnder interferometer (left), while a directional coupler (right) defines a 2 x 2 optical switch. Both switches are electro-optically controlled and optoelectronically integrated. Note the two possible states of each switch.
