Towards massively parallel optical communications and large-scale optical computing, optical modulators with high bandwidth density (Tbps/mm²) are required. To date, various surface-normal modulators incorporating organic electro-optic materials into optical resonators have been demonstrated. However, their modulation bandwidth has been limited to below 20 GHz. In this work, we fabricated a 30-µm-diameter Fabry–Pérot modulator using a low-resistance gold thin film and demonstrated a modulation bandwidth of 40 GHz. The demonstrated device is expected to be scalable to high-density two-dimensional modulator arrays.
