Lithium tantalate photonic integrated circuits for high volume manufacturing

We demonstrate the first photonic integrated circuit platform using Lithium Tantalate (LiTaO 3 ), achieving waveguides with low losses (5.6 dBm −1 ), Mach-Zehnder modulators with a 40 GHz electro-optical bandwidth and a 1.96 V·cm voltage-length product, along with microresonators supporting dissipative Kerr soliton generation.
