Lithium Tantalate Photonic Integrated Circuits (Student Paper)

We demonstrate a wafer-scale lithium tantalate photonic platform with loss as low as 5.5 dB m(-1). Mach-Zehnder modulators with a 40 GHz electro-optical bandwidth and a 1.96 V center dot cm voltage-length product, along with microresonators supporting dissipative Kerr soliton generation.
