报告内容：We proposed a method to simultaneously implement quasi-phase-matching (QPM) second harmonic generation (SHG) and acousto-optic (AO) polarization rotation for arbitrary wavelengths in an aperiodically poled lithium niobate (APPLN). Self-adjusting algorithm (SA) is employed for designing the aperiodic microstructure. The QPM SHG and AO polarization rotation are coupled together. The numerical simulation shows that there is a competition between the SHG and AO polarization rotation, which is dominated by the acoustic intensity that makes the output tunable.
