A new publication from Opto-Electronic Advances; DOI  10.29026/oea.2025.240139 , discusses ferroelectric domain engineering ...

PPLN waveguides can perform this feat thanks to fabrication techniques that create patterns of points on lithium niobate wafers where the crystal’s electric dipole alternately points up or down.

Researchers from the Colorado School of Mines, the China Academy of Science, and EPFL have developed a new ultra-broadband electro-optic comb that can precisely measure light at 450 nm. The ...
