Researchers develop photonic circuit in lithium niobate

Researchers led by Cristina Benea-Chelmus in the Laboratory of Hybrid Photonics (HYLAB) in EPFL’s School of Engineering, ETH Zurich and Harvard University are testing a new thin-film circuit that, when connected to a laser beam, produces finely tailorable terahertz-frequency waves.

The integrated photonic circuit chip is made of lithium niobate.
