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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
