Design of a built-in push-pull AO modulator based on a nonsuspended TFLN-ChG hybrid waveguide platform.

Caption

Schematic diagram and cross-sectional view of the proposed device. The MZI waveguide is etched on the top of the Ge₂₅Sb₁₀S₆₅ film (orange), which is deposited on the LNOI wafer (light blue). The IDT made of Au electrodes (yellow) is evaporated in the region between the two arms. In principle, the direct current (DC) optical input is modulated into a distorted sinusoidal time-domain signal via a varied SAW.
