Summary: The increasing demand for high data rates and low power consumption challenges the capabilities of silicon photonics. The integration of optical ferro-electric materials on the silicon on insulator (SOI) platform enhances its functionality. PZT thin films deposited on SOI substrates show promising relative permittivity and dielectric loss at high frequencies, enabling the possibility of achieving bandwidths beyond 60GHz in next generation data communication systems using Mach-Zehnder modulators.

Summary: Photonic integrated circuits (PICs) at cryogenic temperatures have a wide range of applications in computing and sensing. By using a low-temperature modulator, optical interconnects can be realized to address the limitations of bulky coaxial cables in cryogenic systems. This study demonstrates a compact optical ring resonator modulator with low driving voltage and high-speed data transmission at low temperatures, paving the way for complex cryogenic photonic functionalities and massive data transmission between cryogenic and room-temperature electronics.

Summary: This research demonstrates a highly linear lithium niobate (LN) modulator with an ultra-high spurious-free dynamic range (SFDR) using a ring-assisted Mach-Zehnder interferometer configuration. The modulation does not require active feedback controls to suppress third-order intermodulation distortions (IMD3), resulting in a significant improvement over previous results in the thin-film LN platform.

Summary: This study demonstrates integrated hybrid thin-film lithium niobate (TFLN) electro-optic Mach-Zehnder modulators (MZM) that utilize TFLN bonded to planarized silicon nitride waveguides. The design eliminates the need for TFLN etching or patterning. The MZM achieves a half-wave voltage length product (V pi L) of 0.8 V.cm at 784 nm. MZM devices with modulation lengths of 0.4 cm and 0.8 cm display a broadband electro-optic response, with a 3 dB bandwidth exceeding 100 GHz and a high extinction ratio exceeding 30 dB, showcasing record performance.
