WebQuasi-phase-matching is a technique in nonlinear optics which allows a positive net flow of energy from the pump frequency to the signal and idler frequencies by creating a periodic … Quasi-phase-matching is a technique in nonlinear optics which allows a positive net flow of energy from the pump frequency to the signal and idler frequencies by creating a periodic structure in the nonlinear medium. Momentum is conserved, as is necessary for phase-matching, through an additional momentum … See more In nonlinear optics, the generation of other frequencies is the result of the nonlinear polarization response of the crystal due to fundamental pump frequency. When the crystal axis is flipped, the polarization wave is shifted by … See more This method enables the generation of high-purity hyperentangled two-photon state. In orthogonal quasi-phase matching (OQPM), a thin-layered crystal structure is combined with … See more The following mathematical description assumes a constant pump amplitude. The signal wavelength can be expressed as a sum over the number of domains that exist in the crystal. … See more The domain width is calculated through the use of Sellmeier equation and using wavevector relations. In the case of DFG this relationship holds true See more
