Study on Enhanced Nonlinearity in Ferroelectric Domain Wall
By studying Cherenkov second harmonic generation, it is found that there exists significantly enhanced nonlinearity in ferroelectric domain wall. This enhanced nonlinearity leads to locality of domain wall, which will modulate the phase velocity of the nonlinear polarization and further influence the Cherenkov angle. Extreme Cherenkov second harmonic generation is proposed and demonstrated, which is distinguished from quasi-phase-matched second harmonic generation.
