Abstract
Design-technology co-optimization in co-packaged optics has become important; designing optical modulators would be a good example because their key figure of merits, such as high bandwidth, efficiency, and thermal robustness, will be impacted by the layout, device structure, etc. This work demonstrates a III–V/Si SISCAP Mach–Zehnder modulator utilizing depletion-mode operation, Franz–Keldysh–assisted modulation, and a traveling-wave electrode design, achieving a modulation efficiency of 0.146 V∙cm and an electro-optic bandwidth of 26.3 GHz, corresponding to a record optical modulation amplitude (OMA) line.
