Abstract: Abstract Due to the strong birefringence, symmetrical directional couplers (DCs) are typically polarization-sensitive in the high index contrast platforms. In this letter, we demonstrate polarization-independent directional couplers utilizing orientation-engineered method on the x-cut lithium-niobate-on-insulator (LNOI)… read more here.
