High-speed and stable 532-nm electro-optic modulator on thin-film lithium tantalate

{{output}}
We demonstrate a high-speed, DC-bias-stable Mach-Zehnder electro-optic modulator at 532 nm on a thin-film lithium tantalate on insulator (LTOI) platform. The devices exhibit a minimum half-wave-voltage-length product (VπL) of 0.22 V⋅cm, a propagation loss of... ...
