  • 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.

  • 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.

  • Patent number: 6538794
    Abstract: A device is provided for generating a photonic signal having a phase different from an input photonic signal that is incident on the device. The input photonic signal has an signal frequency, signal bandwidth, and a signal intensity. The device comprises a plurality of material layers. The material layers are arranged such that the device exhibits a photonic band gap structure. The photonic band gap structure exhibits a transmission band edge that corresponds to the input photonic signal frequency. A second photonic signal is generated at a second photonic frequency preferably close to a second band edge. The interaction of the input photonic signal with the second photonic signal generates a phase shift of order &pgr; for relatively small input intensities.

  • Patent number: 6414780
    Abstract: Non-linear reflectivity and non-linear transmissivity of a first photonic signal incident on a photonic band gap (PBG) structure are controlled by applying a second photonic signal to the PBG structure while the first photonic signal is incident on the PBG structure. The first and second photonic signals have respective frequencies near a low frequency, first order band gap edge and a high frequency, second order band gap edge resonance peak of the PBG structure. The first photonic signal undergoes enhanced non-linear gain near the band gap edges when a predetermined phase difference is imposed between the first and second photonic signals, resulting in dramatic reflectivity and transmissivity changes for a band gap structure of only a few microns in length.
