Researchers develop highly efficient ultrabroadband edge coupler

Thin-film lithium niobate (TFLN) is a versatile nanophotonic platform that has recently emerged. TFLN-based periodically poled lithium niobite (PPLN) devices outperform their legacy counterparts in both non-linear optical efficiency and device footprint due to their advantages of high optical confinement, enhanced light-matter interaction, and...

First integrated laser on lithium niobate chip

For all the recent advances in integrated lithium niobate photonic circuits, one big component has remained frustratingly difficult to integrate which is lasers. Long haul telecommunication networks, data centre optical interconnects and microwave photonic systems all rely on lasers to generate an optical carrier used in...
