Fully Packaged 100-GHz-Bandwidth EO-Equalizer-Integrated TFLN Modulator with Record-High Slope Efficiency Enabling 200-GBaud Signaling

We developed a fully packaged $100-\mathrm{GHz}$-bandwidth TFLN modulator utilizing an electro-optic frequency-domain equalizer with record-high slope efficiency, enabling the first measurable TDEC/TDECQ of 200-GbaudOOK and 184-GbaudPAM4 without receiver-side digital equalizers. Furthermore, BER measurements up to 255 Gbaud and 528 Gbps are reported. © 2024 The Author(s)
