Second harmonic generation (SHG) in LiNbO3

    • Pratishtha Agnihotri

      Hello, I want to see the second harmonic generation in LiNbO3. How should I proceed with 180-degree polarization rotation? There is an example given Is there any other suggestion for polarization rotation? I don't need to use a tapered waveguide.

      The 180-deg polarizatio rotation should be realized through propagation where the device has poarizaion effect that causes the polaritzation vector rotating. You may first need to simulate a long device, use a line monitor along propagation to check the polariation rotation.
