Abstract

We propose a transfer-function-transformed optical modulator by introducing a branched asymmetric coplanar waveguide electrode. The structure has the potential to achieve low half-wave voltage and large bandwidth while maintaining its flexibility. We confirmed a linearity improvement with the fabricated modulator.
