Publication number: 20150378183Abstract: A nanophotonic device includes at least two waveguides located on top of a transparent substrate, which form an intersection point at which a part of a first waveguide simultaneously constitutes a part of a second waveguide. A nanoscale element located on top of the intersection point so that it partially or completely covers the intersection point is switchable between two different states, which differ by a refractive index value. The nanophotonic device is operated by injecting at least two optical pulses into the waveguides. Intensity of the optical pulses is selected so that a superposition of the optical pulses switches the nanoscale element into a desired state.
