  • Method and system for determining second-order nonlinear optical coefficients
    Patent number: 9046735
    Abstract: Described herein is a method for determining second-order nonlinear optical coefficients of a material. The method envisages the steps of providing a specimen made at least in part of the material, causing a first optical signal and a second optical signal having, respectively, a first pulsation and a second pulsation, and a first polarization state and a second polarization state, to impinge upon the specimen in such a way that the specimen generates a second-harmonic optical signal having a third pulsation equal to the sum of the first and second pulsations, and a third polarization state that is a function of the first and second polarization states. The method further envisages the step of determining a plurality of measurements of power corresponding to the second-harmonic optical signal, and the step of determining the second-order nonlinear optical coefficients on the basis of the plurality of measurements of power.

  • Optical logic gate
    Patent number: 8520278
    Abstract: Optical logic gate having a second-harmonic generator element that receives a first and a second optical input signal respectively having a first and a second angular frequency and respectively having a first and a second polarization, and which provides a second-harmonic optical signal having a third angular frequency and a third polarization. The third angular frequency is equal to the sum of the first and the second angular frequency. The third polarization is a function of the first and the second polarization. The second-harmonic generator element includes a second-harmonic generator layer in a material having a non-null second-order optical tensor.
