N2 - Integrated nanophotonics using lithium-niobate-on-insulator promises much-awaited solutions for scalable photonics techniques. One of its core functions is electro-optic modulation, which currently suffers limited extinction (<30 dB) due to inevitable fabrication errors. We exploit a cascaded Mach–Zehnder interferometry design to offset those errors, demonstrating up to 53 dB modulation extinction for a wide range of wavelengths between 1500 nm and 1600 nm. Together, its favorable features of chip integration, high extinction, good stability, and being broadband may prove valuable in a plethora of flourishing photonics applications.
